pip无法安装软件包

Question

有人知道这里可能出什么问题吗？ 我正在尝试安装自己的python软件包，但得到：

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):
  File "c:\python\python36\lib\site-packages\pip\_internal\cli\base_command.py",
 line 143, in main
    status = self.run(options, args)

    use_user_site=options.use_user_site,

in move_wheel_files
    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，为什么我得到： AssertionError: xxx .dist-info directory not found ？

删除您的Pip缓存，这是因为，无论您是使用venv还是系统解释器（如果您将Pip用作程序包管理器），都会始终将部分程序包缓存在计算机中。

查看OS PyPi Caching的缓存位置 。
