版本历史

版本	变更
v10.0.0	The `callback` parameter is no longer optional. Not passing it will throw a `TypeError` at runtime.
v7.6.0	The `path` parameter can be a WHATWG `URL` object using `file:` protocol. Support is currently still experimental.
v7.0.0	The `callback` parameter is no longer optional. Not passing it will emit a deprecation warning with id DEP0013.
v0.0.2	新增于: v0.0.2

path <string> | <Buffer> | <URL>
callback <Function>
- err <Error>

异步地删除文件或符号链接。除了可能的异常，完成回调没有其他参数。

// 假设 'path/file.txt' 是常规文件。
fs.unlink('path/file.txt', (err) => {
  if (err) throw err;
  console.log('文件已删除');
});

fs.unlink() 不能用于目录。要删除目录，则使用 fs.rmdir()。

path <string> | <Buffer> | <URL>
callback <Function>
- err <Error>

Asynchronously removes a file or symbolic link. No arguments other than a possible exception are given to the completion callback.

// Assuming that 'path/file.txt' is a regular file.
fs.unlink('path/file.txt', (err) => {
  if (err) throw err;
  console.log('path/file.txt was deleted');
});

fs.unlink() will not work on a directory, empty or otherwise. To remove a directory, use fs.rmdir().
