path.dirname(path)

• path <string>

• 返回：<string>

  ¥Returns: <string>

path.dirname() 方法返回 path 的目录名，类似于 Unix dirname 命令。尾随的目录分隔符被忽略，见 path.sep。

¥The path.dirname() method returns the directory name of a path, similar to the Unix dirname command. Trailing directory separators are ignored, see path.sep.

path.dirname('/foo/bar/baz/asdf/quux');
// Returns: '/foo/bar/baz/asdf' 拷贝

如果 path 不是字符串，则抛出 TypeError。

¥A TypeError is thrown if path is not a string.
