python下载package失败,pip安装packag失败
有人知道这里出了什么问题吗？我正在尝试安装我自己的python包，但是得到了：c:\Python\Python36\Scripts>pip install --index-url yyy xxx
Looking in indexes: yyy
Collecting xxx
Installing collected packages: xxx
Exception:
Traceback (most recent call last):

assert info_dir, "%s .dist-info directory not found" % req
AssertionError: xxx .dist-info directory not found
python或pip可能有什么问题，以及为什么我得到：
AssertionError: xxx .dist-info directory not found？在
