错误#

Errors

在 Node.js 中运行的应用通常会遇到四类错误:

Applications running in Node.js will generally experience four categories of errors:

  • 标准的 JavaScript 错误,例如 <EvalError><SyntaxError><RangeError><ReferenceError><TypeError><URIError>

    Standard JavaScript errors such as <EvalError>, <SyntaxError>, <RangeError>, <ReferenceError>, <TypeError>, and <URIError>.

  • 由底层操作系统约束触发的系统错误,例如尝试打开不存在的文件或尝试通过关闭的套接字发送数据。

    System errors triggered by underlying operating system constraints such as attempting to open a file that does not exist or attempting to send data over a closed socket.

  • 由应用代码触发的用户指定的错误。

    User-specified errors triggered by application code.

  • AssertionError 是一类特殊的错误,当 Node.js 检测到不应该发生的异常逻辑违规时会触发该错误。这些通常由 node:assert 模块引发。

    AssertionErrors are a special class of error that can be triggered when Node.js detects an exceptional logic violation that should never occur. These are raised typically by the node:assert module.

Node.js 引发的所有 JavaScript 和系统错误都继承自标准 JavaScript <Error> 类,或者是标准 JavaScript <Error> 类的实例,并且保证至少提供该类上可用的属性。

All JavaScript and system errors raised by Node.js inherit from, or are instances of, the standard JavaScript <Error> class and are guaranteed to provide at least the properties available on that class.

错误冒泡和拦截#

Error propagation and interception

Node.js 支持多种机制来传播和处理应用运行时发生的错误。如何报告和处理这些错误完全取决于 Error 的类型和调用的 API 的风格。

Node.js supports several mechanisms for propagating and handling errors that occur while an application is running. How these errors are reported and handled depends entirely on the type of Error and the style of the API that is called.

所有 JavaScript 错误都作为异常处理,使用标准 JavaScript throw 机制立即生成并抛出错误。这些是使用 JavaScript 语言提供的 try…catch 构造 来处理的。

All JavaScript errors are handled as exceptions that immediately generate and throw an error using the standard JavaScript throw mechanism. These are handled using the try…catch construct provided by the JavaScript language.

// Throws with a ReferenceError because z is not defined.
try {
  const m = 1;
  const n = m + z;
} catch (err) {
  // Handle the error here.
} 

对 JavaScript throw 机制的任何使用都会引发必须处理的异常,否则 Node.js 进程将立即退出。

Any use of the JavaScript throw mechanism will raise an exception that must be handled or the Node.js process will exit immediately.

除了少数例外,同步 API(任何不返回 <Promise> 也不接受 callback 函数的阻塞方法,例如 fs.readFileSync)将使用 throw 来报告错误。

With few exceptions, Synchronous APIs (any blocking method that does not return a <Promise> nor accept a callback function, such as fs.readFileSync), will use throw to report errors.

异步 API 中发生的错误可能会以多种方式报告:

Errors that occur within Asynchronous APIs may be reported in multiple ways:

  • 某些异步方法返回 <Promise>,你应该始终考虑到它可能会被拒绝。请参阅 --unhandled-rejections 标志,了解进程如何对未处理的 promise 拒绝做出反应。

    Some asynchronous methods returns a <Promise>, you should always take into account that it might be rejected. See --unhandled-rejections flag for how the process will react to an unhandled promise rejection.

    const fs = require('fs/promises');
    
    (async () => {
      let data;
      try {
        data = await fs.readFile('a file that does not exist');
      } catch (err) {
        console.error('There was an error reading the file!', err);
        return;
      }
      // Otherwise handle the data
    })(); 
  • 大多数接受 callback 函数的异步方法将接受作为第一个参数传给该函数的 Error 对象。如果第一个参数不是 null 并且是 Error 的实例,则发生了应该处理的错误。

    Most asynchronous methods that accept a callback function will accept an Error object passed as the first argument to that function. If that first argument is not null and is an instance of Error, then an error occurred that should be handled.

    const fs = require('node:fs');
    fs.readFile('a file that does not exist', (err, data) => {
      if (err) {
        console.error('There was an error reading the file!', err);
        return;
      }
      // Otherwise handle the data
    }); 
  • 当在 EventEmitter 对象上调用异步方法时,错误可以路由到该对象的 'error' 事件。

    When an asynchronous method is called on an object that is an EventEmitter, errors can be routed to that object's 'error' event.

    const net = require('node:net');
    const connection = net.connect('localhost');
    
    // Adding an 'error' event handler to a stream:
    connection.on('error', (err) => {
      // If the connection is reset by the server, or if it can't
      // connect at all, or on any sort of error encountered by
      // the connection, the error will be sent here.
      console.error(err);
    });
    
    connection.pipe(process.stdout); 
  • Node.js API 中的一些典型的异步方法可能仍然使用 throw 机制来引发必须使用 try…catch 处理的异常。没有此类方法的完整列表;请参考每种方法的文档以确定所需的适当错误处理机制。

    A handful of typically asynchronous methods in the Node.js API may still use the throw mechanism to raise exceptions that must be handled using try…catch. There is no comprehensive list of such methods; please refer to the documentation of each method to determine the appropriate error handling mechanism required.

'error' 事件机制的使用最常见于 stream-based基于事件触发器 API,它们本身代表随时间推移的一系列异步操作(与可能通过或失败的单个操作相反)。

The use of the 'error' event mechanism is most common for stream-based and event emitter-based APIs, which themselves represent a series of asynchronous operations over time (as opposed to a single operation that may pass or fail).

对于所有 EventEmitter 对象,如果没有提供 'error' 事件处理程序,将抛出错误,导致 Node.js 进程报告未捕获的异常并崩溃,除非:已为 'uncaughtException' 事件注册了处理程序,或者使用了已弃用的 node:domain 模块。

For all EventEmitter objects, if an 'error' event handler is not provided, the error will be thrown, causing the Node.js process to report an uncaught exception and crash unless either: a handler has been registered for the 'uncaughtException' event, or the deprecated node:domain module is used.

const EventEmitter = require('node:events');
const ee = new EventEmitter();

setImmediate(() => {
  // This will crash the process because no 'error' event
  // handler has been added.
  ee.emit('error', new Error('This will crash'));
}); 

以这种方式产生的错误无法使用 try…catch 拦截,因为它们是在调用代码已经退出后抛出的。

Errors generated in this way cannot be intercepted using try…catch as they are thrown after the calling code has already exited.

开发者必须参考每种方法的文档,以确定这些方法引发的错误是如何传播的。

Developers must refer to the documentation for each method to determine exactly how errors raised by those methods are propagated.

类:Error#

Class: Error

通用的 JavaScript <Error> 对象,不表示发生错误的任何具体情况。Error 对象捕获 "堆栈跟踪",详细说明代码中实例化 Error 的点,并可能提供错误的文本描述。

A generic JavaScript <Error> object that does not denote any specific circumstance of why the error occurred. Error objects capture a "stack trace" detailing the point in the code at which the Error was instantiated, and may provide a text description of the error.

Node.js 生成的所有错误,包括所有系统和 JavaScript 错误,都将是 Error 类的实例或继承自 Error 类。

All errors generated by Node.js, including all system and JavaScript errors, will either be instances of, or inherit from, the Error class.

new Error(message[, options])#

  • message <string>

  • options <Object>

    • cause <any> 导致新创建的错误的错误。

      cause <any> The error that caused the newly created error.

创建新的 Error 对象并将 error.message 属性设置为提供的文本消息。如果对象作为 message 传入,则通过调用 String(message) 生成文本消息。如果提供了 cause 选项,则将其分配给 error.cause 属性。error.stack 属性将代表代码中调用 new Error() 的点。堆栈跟踪依赖于 V8 的堆栈跟踪 API。堆栈跟踪仅扩展到 (a) 同步代码执行的开始,或 (b) 属性 Error.stackTraceLimit 给出的帧数,以较小者为准。

Creates a new Error object and sets the error.message property to the provided text message. If an object is passed as message, the text message is generated by calling String(message). If the cause option is provided, it is assigned to the error.cause property. The error.stack property will represent the point in the code at which new Error() was called. Stack traces are dependent on V8's stack trace API. Stack traces extend only to either (a) the beginning of synchronous code execution, or (b) the number of frames given by the property Error.stackTraceLimit, whichever is smaller.

Error.captureStackTrace(targetObject[, constructorOpt])#

targetObject 上创建 .stack 属性,访问时返回表示调用 Error.captureStackTrace() 的代码中的位置的字符串。

Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack;  // Similar to `new Error().stack` 

跟踪的第一行将以 ${myObject.name}: ${myObject.message} 为前缀。

The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

可选的 constructorOpt 参数接受一个函数。如果给定,则所有 constructorOpt 以上的帧,包括 constructorOpt,都将从生成的堆栈跟踪中省略。

The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

constructorOpt 参数对于向用户隐藏错误生成的实现细节很有用。例如:

The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

function a() {
  b();
}

function b() {
  c();
}

function c() {
  // Create an error without stack trace to avoid calculating the stack trace twice.
  const { stackTraceLimit } = Error;
  Error.stackTraceLimit = 0;
  const error = new Error();
  Error.stackTraceLimit = stackTraceLimit;

  // Capture the stack trace above function b
  Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
  throw error;
}

a(); 

Error.stackTraceLimit#

Error.stackTraceLimit 属性指定堆栈跟踪收集的堆栈帧数(无论是由 new Error().stack 还是 Error.captureStackTrace(obj) 生成)。

The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

默认值为 10,但可以设置为任何有效的 JavaScript 数值。更改将影响值更改后捕获的任何堆栈跟踪。

The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

如果设置为非数字值,或设置为负数,则堆栈跟踪将不会捕获任何帧。

If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

error.cause#

如果存在,则 error.cause 属性是 Error 的根本原因。当捕获一个错误并抛出一个带有不同消息或代码的新错误以便仍然可以访问原始错误时使用它。

If present, the error.cause property is the underlying cause of the Error. It is used when catching an error and throwing a new one with a different message or code in order to still have access to the original error.

error.cause 属性通常通过调用 new Error(message, { cause }) 来设置。如果没有提供 cause 选项,则不是构造函数设置的。

The error.cause property is typically set by calling new Error(message, { cause }). It is not set by the constructor if the cause option is not provided.

此属性允许链接错误。当序列化 Error 对象时,如果设置了 util.inspect(),则递归序列化 error.cause

This property allows errors to be chained. When serializing Error objects, util.inspect() recursively serializes error.cause if it is set.

const cause = new Error('The remote HTTP server responded with a 500 status');
const symptom = new Error('The message failed to send', { cause });

console.log(symptom);
// Prints:
//   Error: The message failed to send
//       at REPL2:1:17
//       at Script.runInThisContext (node:vm:130:12)
//       ... 7 lines matching cause stack trace ...
//       at [_line] [as _line] (node:internal/readline/interface:886:18) {
//     [cause]: Error: The remote HTTP server responded with a 500 status
//         at REPL1:1:15
//         at Script.runInThisContext (node:vm:130:12)
//         at REPLServer.defaultEval (node:repl:574:29)
//         at bound (node:domain:426:15)
//         at REPLServer.runBound [as eval] (node:domain:437:12)
//         at REPLServer.onLine (node:repl:902:10)
//         at REPLServer.emit (node:events:549:35)
//         at REPLServer.emit (node:domain:482:12)
//         at [_onLine] [as _onLine] (node:internal/readline/interface:425:12)
//         at [_line] [as _line] (node:internal/readline/interface:886:18) 

error.code#

error.code 属性是标识错误类型的字符串标签。error.code 是识别错误的最稳定方式。它只会在 Node.js 的主要版本之间发生变化。相比之下,error.message 字符串可能会在任何版本的 Node.js 之间发生变化。有关具体代码的详细信息,请参见 Node.js 错误代码

The error.code property is a string label that identifies the kind of error. error.code is the most stable way to identify an error. It will only change between major versions of Node.js. In contrast, error.message strings may change between any versions of Node.js. See Node.js error codes for details about specific codes.

error.message#

error.message 属性是通过调用 new Error(message) 设置的错误的字符串描述。传递给构造函数的 message 也会出现在 Error 的堆栈跟踪的第一行,但是在创建 Error 对象后更改此属性可能不会更改堆栈跟踪的第一行(例如,当之前读取 error.stack 时 此属性已更改)。

The error.message property is the string description of the error as set by calling new Error(message). The message passed to the constructor will also appear in the first line of the stack trace of the Error, however changing this property after the Error object is created may not change the first line of the stack trace (for example, when error.stack is read before this property is changed).

const err = new Error('The message');
console.error(err.message);
// Prints: The message 

error.stack#

error.stack 属性是描述代码中实例化 Error 的点的字符串。

The error.stack property is a string describing the point in the code at which the Error was instantiated.

Error: Things keep happening!
   at /home/gbusey/file.js:525:2
   at Frobnicator.refrobulate (/home/gbusey/business-logic.js:424:21)
   at Actor.<anonymous> (/home/gbusey/actors.js:400:8)
   at increaseSynergy (/home/gbusey/actors.js:701:6) 

第一行的格式为 <error class name>: <error message>,后面是一系列堆栈帧(每行以 "at" 开头)。每一帧都描述了代码中导致错误生成的调用点。V8 尝试为每个函数显示名称(通过变量名、函数名、或对象方法名),但偶尔会找不到合适的名称。如果 V8 无法确定函数的名称,则只会显示该帧的位置信息。否则,将显示确定的函数名称,括号中会附加位置信息。

The first line is formatted as <error class name>: <error message>, and is followed by a series of stack frames (each line beginning with "at "). Each frame describes a call site within the code that lead to the error being generated. V8 attempts to display a name for each function (by variable name, function name, or object method name), but occasionally it will not be able to find a suitable name. If V8 cannot determine a name for the function, only location information will be displayed for that frame. Otherwise, the determined function name will be displayed with location information appended in parentheses.

帧仅为 JavaScript 函数生成。例如,如果执行同步通过名为 cheetahify 的 C++ 插件函数,该函数本身调用 JavaScript 函数,则表示 cheetahify 调用的帧将不会出现在堆栈跟踪中:

Frames are only generated for JavaScript functions. If, for example, execution synchronously passes through a C++ addon function called cheetahify which itself calls a JavaScript function, the frame representing the cheetahify call will not be present in the stack traces:

const cheetahify = require('./native-binding.node');

function makeFaster() {
  // `cheetahify()` *synchronously* calls speedy.
  cheetahify(function speedy() {
    throw new Error('oh no!');
  });
}

makeFaster();
// will throw:
//   /home/gbusey/file.js:6
//       throw new Error('oh no!');
//           ^
//   Error: oh no!
//       at speedy (/home/gbusey/file.js:6:11)
//       at makeFaster (/home/gbusey/file.js:5:3)
//       at Object.<anonymous> (/home/gbusey/file.js:10:1)
//       at Module._compile (module.js:456:26)
//       at Object.Module._extensions..js (module.js:474:10)
//       at Module.load (module.js:356:32)
//       at Function.Module._load (module.js:312:12)
//       at Function.Module.runMain (module.js:497:10)
//       at startup (node.js:119:16)
//       at node.js:906:3 

位置信息将是以下之一:

The location information will be one of:

  • native, 如果帧代表 V8 内部的调用(如 [].forEach)。

    native, if the frame represents a call internal to V8 (as in [].forEach).

  • plain-filename.js:line:column, 如果帧代表 Node.js 内部调用

    plain-filename.js:line:column, if the frame represents a call internal to Node.js.

  • 如果帧代表用户程序中的调用(使用 CommonJS 模块系统)或其依赖,则为 /absolute/path/to/file.js:line:column

    /absolute/path/to/file.js:line:column, if the frame represents a call in a user program (using CommonJS module system), or its dependencies.

  • 如果帧代表用户程序中的调用(使用 ES 模块系统)或其依赖,则为 <transport-protocol>:///url/to/module/file.mjs:line:column

    <transport-protocol>:///url/to/module/file.mjs:line:column, if the frame represents a call in a user program (using ES module system), or its dependencies.

当访问 error.stack 属性时,会延迟生成表示堆栈跟踪的字符串。

The string representing the stack trace is lazily generated when the error.stack property is accessed.

堆栈跟踪捕获的帧数以 Error.stackTraceLimit 或当前事件循环刻度上的可用帧数中的较小者为界。

The number of frames captured by the stack trace is bounded by the smaller of Error.stackTraceLimit or the number of available frames on the current event loop tick.

类:AssertionError#

Class: AssertionError

表示断言的失败。详情见 Class: assert.AssertionError

Indicates the failure of an assertion. For details, see Class: assert.AssertionError.

类:RangeError#

Class: RangeError

表示提供的参数不在函数可接受值的集合或范围内;这是一个数字范围,还是超出给定函数参数的选项集。

Indicates that a provided argument was not within the set or range of acceptable values for a function; whether that is a numeric range, or outside the set of options for a given function parameter.

require('node:net').connect(-1);
// Throws "RangeError: "port" option should be >= 0 and < 65536: -1" 

Node.js 将立即生成并抛出 RangeError 实例作为参数验证的一种形式。

Node.js will generate and throw RangeError instances immediately as a form of argument validation.

类:ReferenceError#

Class: ReferenceError

表示正在尝试访问未定义的变量。此类错误通常表示代码中存在拼写错误或程序损坏。

Indicates that an attempt is being made to access a variable that is not defined. Such errors commonly indicate typos in code, or an otherwise broken program.

虽然客户端代码可能会产生和传播这些错误,但实际上只有 V8 会这样做。

While client code may generate and propagate these errors, in practice, only V8 will do so.

doesNotExist;
// Throws ReferenceError, doesNotExist is not a variable in this program. 

除非应用动态生成和运行代码,否则 ReferenceError 实例表明代码或其依赖中存在错误。

Unless an application is dynamically generating and running code, ReferenceError instances indicate a bug in the code or its dependencies.

类:SyntaxError#

Class: SyntaxError

表示程序不是有效的 JavaScript。这些错误只能作为代码评估的结果生成和传播。代码评估可能作为 evalFunctionrequirevm 的结果发生。这些错误几乎始终表明程序损坏。

Indicates that a program is not valid JavaScript. These errors may only be generated and propagated as a result of code evaluation. Code evaluation may happen as a result of eval, Function, require, or vm. These errors are almost always indicative of a broken program.

try {
  require('node:vm').runInThisContext('binary ! isNotOk');
} catch (err) {
  // 'err' will be a SyntaxError.
} 

SyntaxError 实例在创建它们的上下文中是不可恢复的 - 它们只能被其他上下文捕获。

SyntaxError instances are unrecoverable in the context that created them – they may only be caught by other contexts.

类:SystemError#

Class: SystemError

Node.js 在其运行时环境中发生异常时会生成系统错误。这些通常发生在应用违反操作系统约束时。例如,如果应用尝试读取不存在的文件,则会发生系统错误。

Node.js generates system errors when exceptions occur within its runtime environment. These usually occur when an application violates an operating system constraint. For example, a system error will occur if an application attempts to read a file that does not exist.

If present, error.dest is the file path destination when reporting a file system error.

error.errno#

error.errno 属性是对应于 libuv Error handling 中定义的错误码的负数。

The error.errno property is a negative number which corresponds to the error code defined in libuv Error handling.

在 Windows 上,系统提供的错误号将由 libuv 规范化。

On Windows the error number provided by the system will be normalized by libuv.

要获取错误码的字符串表示,则使用 util.getSystemErrorName(error.errno)

To get the string representation of the error code, use util.getSystemErrorName(error.errno).

error.info#

如果存在,则 error.info 是包含错误情况详细信息的对象。

If present, error.info is an object with details about the error condition.

常见系统错误#

Common system errors

这是编写 Node.js 程序时经常遇到的系统错误列表。有关完整列表,请参阅 errno(3) 手册页

This is a list of system errors commonly-encountered when writing a Node.js program. For a comprehensive list, see the errno(3) man page.

  • EACCES(权限被拒绝):试图以文件访问权限禁止的方式访问文件。

    EACCES (Permission denied): An attempt was made to access a file in a way forbidden by its file access permissions.

  • EADDRINUSE(地址已被使用):由于本地系统上的另一台服务器已占用该地址,尝试将服务器(nethttphttps)绑定到本地地址失败。

    EADDRINUSE (Address already in use): An attempt to bind a server (net, http, or https) to a local address failed due to another server on the local system already occupying that address.

  • ECONNREFUSED(连接被拒绝):由于目标机器主动拒绝,无法建立连接。这通常是由于尝试连接到在外部主机上处于非活动状态的服务。

    ECONNREFUSED (Connection refused): No connection could be made because the target machine actively refused it. This usually results from trying to connect to a service that is inactive on the foreign host.

  • ECONNRESET(对等方重置连接):连接被对等方强行关闭。这通常是由于超时或重新启动导致远程套接字上的连接丢失造成的。通常通过 httpnet 模块遇到。

    ECONNRESET (Connection reset by peer): A connection was forcibly closed by a peer. This normally results from a loss of the connection on the remote socket due to a timeout or reboot. Commonly encountered via the http and net modules.

  • EEXIST(文件存在):现有文件是要求目标不存在的操作的目标。

    EEXIST (File exists): An existing file was the target of an operation that required that the target not exist.

  • EISDIR(是一个目录):一个操作需要一个文件,但给定的路径名是一个目录。

    EISDIR (Is a directory): An operation expected a file, but the given pathname was a directory.

  • EMFILE(系统中打开的文件太多):已达到系统允许的最大 文件描述符 数量,并且在至少关闭一个描述符之前无法满足对另一个描述符的请求。同时打开多个文件时会遇到这种情况,尤其是在进程的文件描述符限制较低的系统(特别是 macOS)上。要弥补低限制,则在将运行 Node.js 进程的同一个 shell 中运行 ulimit -n 2048

    EMFILE (Too many open files in system): Maximum number of file descriptors allowable on the system has been reached, and requests for another descriptor cannot be fulfilled until at least one has been closed. This is encountered when opening many files at once in parallel, especially on systems (in particular, macOS) where there is a low file descriptor limit for processes. To remedy a low limit, run ulimit -n 2048 in the same shell that will run the Node.js process.

  • ENOENT(没有这样的文件或目录):通常由 fs 操作引发以指示指定路径名的组件不存在。给定路径找不到任何实体(文件或目录)。

    ENOENT (No such file or directory): Commonly raised by fs operations to indicate that a component of the specified pathname does not exist. No entity (file or directory) could be found by the given path.

  • ENOTDIR(不是目录):给定路径名的组件存在,但不是预期的目录。通常由 fs.readdir 引起。

    ENOTDIR (Not a directory): A component of the given pathname existed, but was not a directory as expected. Commonly raised by fs.readdir.

  • ENOTEMPTY(目录非空):包含条目的目录是需要空目录(通常为 fs.unlink)的操作的目标。

    ENOTEMPTY (Directory not empty): A directory with entries was the target of an operation that requires an empty directory, usually fs.unlink.

  • ENOTFOUND(DNS 查找失败):指示 EAI_NODATAEAI_NONAME 的 DNS 故障。这不是标准的 POSIX 错误。

    ENOTFOUND (DNS lookup failed): Indicates a DNS failure of either EAI_NODATA or EAI_NONAME. This is not a standard POSIX error.

  • EPERM(不允许操作):试图执行需要提升权限的操作。

    EPERM (Operation not permitted): An attempt was made to perform an operation that requires elevated privileges.

  • EPIPE(破管):在没有进程读取数据的管道、套接字或 FIFO 上写入。通常发生在 nethttp 层,表示正在写入的流的远程端已关闭。

    EPIPE (Broken pipe): A write on a pipe, socket, or FIFO for which there is no process to read the data. Commonly encountered at the net and http layers, indicative that the remote side of the stream being written to has been closed.

  • ETIMEDOUT(操作超时):连接或发送请求失败,因为连接方在一段时间后没有正确响应。通常发生在 httpnet。通常表明 socket.end() 没有被正确地调用。

    ETIMEDOUT (Operation timed out): A connect or send request failed because the connected party did not properly respond after a period of time. Usually encountered by http or net. Often a sign that a socket.end() was not properly called.

类:TypeError#

Class: TypeError

表示提供的参数不是允许的类型。例如,将函数传给期望字符串为 TypeError 的参数。

Indicates that a provided argument is not an allowable type. For example, passing a function to a parameter which expects a string would be a TypeError.

Node.js will generate and throw TypeError instances immediately as a form of argument validation.

异常与错误#

Exceptions vs. errors

JavaScript 异常是由于无效操作或作为 throw 语句的目标而抛出的值。虽然不要求这些值是 Error 的实例或从 Error 继承的类,但 Node.js 或 JavaScript 运行时抛出的所有异常都将是 Error 的实例。

A JavaScript exception is a value that is thrown as a result of an invalid operation or as the target of a throw statement. While it is not required that these values are instances of Error or classes which inherit from Error, all exceptions thrown by Node.js or the JavaScript runtime will be instances of Error.

有些异常在 JavaScript 层是不可恢复的。这种异常总是会导致 Node.js 进程崩溃。示例包括 C++ 层中的 assert() 检查或 abort() 调用。

Some exceptions are unrecoverable at the JavaScript layer. Such exceptions will always cause the Node.js process to crash. Examples include assert() checks or abort() calls in the C++ layer.

OpenSSL 错误#

OpenSSL errors

源自 cryptotls 的错误属于 Error 类,除了标准的 .code.message 属性外,可能还有一些额外的 OpenSSL 特定属性。

Errors originating in crypto or tls are of class Error, and in addition to the standard .code and .message properties, may have some additional OpenSSL-specific properties.

error.opensslErrorStack#

可以为 OpenSSL 库中错误源自的位置提供上下文的错误数组。

An array of errors that can give context to where in the OpenSSL library an error originates from.

error.function#

错误源自的 OpenSSL 函数。

The OpenSSL function the error originates in.

error.library#

错误源自的 OpenSSL 库。

The OpenSSL library the error originates in.

error.reason#

描述错误原因的人类可读的字符串。

A human-readable string describing the reason for the error.

Node.js 错误代码#

Node.js error codes

ABORT_ERR#

当操作中止时使用(通常使用 AbortController)。

Used when an operation has been aborted (typically using an AbortController).

不使用 AbortSignal 的 API 通常不会引发此代码的错误。

APIs not using AbortSignals typically do not raise an error with this code.

此代码未使用 Node.js 错误使用的常规 ERR_* 约定,以便与网络平台的 AbortError 兼容。

This code does not use the regular ERR_* convention Node.js errors use in order to be compatible with the web platform's AbortError.

ERR_ACCESS_DENIED#

每当 Node.js 尝试访问受 policy 清单限制的资源时,就会触发一种特殊类型的错误。例如,process.binding

A special type of error that is triggered whenever Node.js tries to get access to a resource restricted by the policy manifest. For example, process.binding.

ERR_AMBIGUOUS_ARGUMENT#

函数参数的使用方式表明函数签名可能会被误解。当 assert.throws(block, message) 中的 message 参数与 block 抛出的错误消息匹配时,则由 node:assert 模块抛出错误,因为这种用法表明用户认为 message 是预期的消息,而不是 block 不抛出时 AssertionError 将显示的消息。

A function argument is being used in a way that suggests that the function signature may be misunderstood. This is thrown by the node:assert module when the message parameter in assert.throws(block, message) matches the error message thrown by block because that usage suggests that the user believes message is the expected message rather than the message the AssertionError will display if block does not throw.

ERR_ARG_NOT_ITERABLE#

需要可迭代的参数(即适用于 for...of 循环的值),但未提供给 Node.js API。

An iterable argument (i.e. a value that works with for...of loops) was required, but not provided to a Node.js API.

ERR_ASSERTION#

特殊类型的错误,每当 Node.js 检测到不应该发生的异常逻辑违规时就会触发。这些通常由 node:assert 模块引发。

A special type of error that can be triggered whenever Node.js detects an exceptional logic violation that should never occur. These are raised typically by the node:assert module.

An attempt was made to create a Node.js Buffer instance from addon or embedder code, while in a JS engine Context that is not associated with a Node.js instance. The data passed to the Buffer method will have been released by the time the method returns.

当遇到此错误时,创建 Buffer 实例的一种可能的替代方法是创建普通的 Uint8Array,它仅在生成的对象的原型上有所不同。Uint8Array 在所有 Node.js 核心 API 中普遍接受,而 Buffer 是;它们在所有上下文中都可用。

When encountering this error, a possible alternative to creating a Buffer instance is to create a normal Uint8Array, which only differs in the prototype of the resulting object. Uint8Arrays are generally accepted in all Node.js core APIs where Buffers are; they are available in all Contexts.
