SystemError 类

• 继承自: <errors.Error>

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程序违反操作系统约束时。 例如，如果应用程序尝试读取不存在的文件，则会发生系统错误。

• address <string> 如果存在，则为网络连接失败的地址
• code <string> 字符串错误码
• dest <string> 如果存在，则为报告文件系统错误时的文件路径目标
• errno <number> | <string> 系统提供的错误号
• info <Object> 如果存在，则为关于错误情况的额外细节
• message <string> 系统提供的人类可读的错误描述
• path <string> 如果存在，则为报告文件系统错误时的文件路径
• port <number> 如果存在，则为不可用的网络连接端口
• syscall <string> 触发错误的系统调用名称

• Extends: <errors.Error>

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.

• address <string> If present, the address to which a network connection failed
• code <string> The string error code
• dest <string> If present, the file path destination when reporting a file system error
• errno <number> | <string> The system-provided error number
• info <Object> If present, extra details about the error condition
• message <string> A system-provided human-readable description of the error
• path <string> If present, the file path when reporting a file system error
• port <number> If present, the network connection port that is not available
• syscall <string> The name of the system call that triggered the error
