fs.mkdir(path[, options], callback)
-
callback<Function>-
err<Error> -
path<string> | <undefined> 仅当创建目录时将recursive设置为true。¥
path<string> | <undefined> Present only if a directory is created withrecursiveset totrue.
-
异步地创建目录。
¥Asynchronously creates a directory.
回调给出一个可能的异常和创建的第一个目录路径(如果 recursive 为 true),(err[, path])。当 recursive 为 true 时,如果没有创建目录,则 path 仍然为 undefined。
¥The callback is given a possible exception and, if recursive is true, the
first directory path created, (err[, path]).
path can still be undefined when recursive is true, if no directory was
created.
可选的 options 参数可以是指定 mode(权限和粘性位)的整数,也可以是具有 mode 属性和 recursive 属性(指示是否应创建父目录)的对象。当 path 是已存在的目录时,调用 fs.mkdir() 仅在 recursive 为 false 时才导致错误。
¥The optional options argument can be an integer specifying mode (permission
and sticky bits), or an object with a mode property and a recursive
property indicating whether parent directories should be created. Calling
fs.mkdir() when path is a directory that exists results in an error only
when recursive is false.
import { mkdir } from 'node:fs';
// Creates /tmp/a/apple, regardless of whether `/tmp` and /tmp/a exist.
mkdir('/tmp/a/apple', { recursive: true }, (err) => {
if (err) throw err;
}); 在 Windows 上,即使使用递归,在根目录上使用 fs.mkdir() 也会导致错误:
¥On Windows, using fs.mkdir() on the root directory even with recursion will
result in an error:
import { mkdir } from 'node:fs';
mkdir('/', { recursive: true }, (err) => {
// => [Error: EPERM: operation not permitted, mkdir 'C:\']
