传入非字符串作为 path 参数现在将抛出错误。

v0.1.25

新增于: v0.1.25

    path.basename() 方法返回 path 的最后一部分，类似于 Unix basename 命令。 尾随的目录分隔符被忽略，见 path.sep。

    The path.basename() method returns the last portion of a path, similar to
the Unix basename command. Trailing directory separators are ignored, see
path.sep.
    path.basename('/foo/bar/baz/asdf/quux.html');
// Returns: 'quux.html'

path.basename('/foo/bar/baz/asdf/quux.html', '.html');
// Returns: 'quux'
    Although Windows usually treats file names, including file extensions, in a
case-insensitive manner, this function does not. For example, C:\\foo.html and
C:\\foo.HTML refer to the same file, but basename treats the extension as a
case-sensitive string:
    path.win32.basename('C:\\foo.html', '.html');
// Returns: 'foo'

path.win32.basename('C:\\foo.HTML', '.html');
// Returns: 'foo.HTML'
    A TypeError is thrown if path is not a string or if ext is given
and is not a string.
