fs.mkdir(path[, options], callback)
异步地创建目录。
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 path
是已存在的目录时,调用 fs.mkdir()
仅在 recursive
为 false 时才导致错误。
// 创建 /tmp/a/apple,不管 `/tmp` 和 /tmp/a 是否存在。
fs.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:
fs.mkdir('/', { recursive: true }, (err) => {
// => [Error: EPERM: operation not permitted, mkdir 'C:\']
});
另见: mkdir(2)
。
Asynchronously creates a directory.
The callback is given a possible exception and, if recursive
is true
, the
first directory path created, (err, [path])
.
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.
// Creates /tmp/a/apple, regardless of whether `/tmp` and /tmp/a exist.
fs.mkdir('/tmp/a/apple', { recursive: true }, (err) => {
if (err) throw err;
});
On Windows, using fs.mkdir()
on the root directory even with recursion will
result in an error:
fs.mkdir('/', { recursive: true }, (err) => {
// => [Error: EPERM: operation not permitted, mkdir 'C:\']
});
