ali.download_file很难直接使用

file_path = ali.download_file(ali.get_file_by_path(‘xxx.mp3’))
会报以下错误
TypeError: download_file() takes 1 positional argument but 2 were given

我只能看仓库源代码去了，看了一会儿使用download_files，多加个s，使用数组传进去，好像可以了！阿里云python下载单个文件，还是要用 download_files，传一个数组进去，

    :Example:
    >>> from aligo import Aligo
    >>> ali = Aligo()
    >>> # noinspection PyShadowingNames
    >>> file_path = ali.download_files([ali.get_file_by_path('xxx.mp3')])
    >>> print(file_path)

可能是download_file，写得有点bug
