pip無法安裝軟件包

Question

有人知道這里可能出什么問題嗎？ 我正在嘗試安裝自己的python軟件包，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)
  File "c:\python\python36\lib\site-packages\pip\_internal\commands\install.py",

    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可能有什么問題，為什么我得到： AssertionError: xxx .dist-info directory not found ？

刪除您的Pip緩存，這是因為，無論您是使用venv還是系統解釋器（如果您將Pip用作程序包管理器），都會始終將部分程序包緩存在計算機中。

查看OS PyPi Caching的緩存位置 。
