C:\Users\cy>pip uninstall pyqt5我使用的是版本是python3.9 win10
始终无法解决消除pip命令的警告
删除 x:\x\python3x\lib\site-packages\~ip* 这个波浪线开头的目录就可以了，可能是 pip 旧版本备份。
同样，-yqt5 其实是 pyqt5吧，对应 site-packages\~yqt5* 目录，删除就可以了。
如果还不行，可以卸载python，删除目录，重新安装所有组件。可以将安装过程做成一个脚本，方便随时安装新环境。
我是暂时先用`python -m pip install --upgrade pip==21.0.1`返回到pip的上一个版本了，使用上一个版本的时候就不会出现WARNING信息，然后准备等找到解决办法了再升级
https://blog.csdn.net/qq_47750984/article/details/117357267
方法可行
目录site-packages下删除~ip开头的目录
尝试重新覆盖安装pyqt5，没有效果
可能是有安装包没有正常完成安装导致，如何排除故障呢

这种情况发生一般都是版本问题，兼容性出了问题，最新版本的pip的原因，建议采用python3.7或者3.8版本，尽量不要使用最新的版本python
在CMD—enter—Python—enter—import numpy如果没有报错就表示没事儿
是安装包没有正常完成安装导致，有人通过以下方法解决的，可借鉴一下，就是到site-packages中查找带前破折号的上述警告信息中所提到的两个破损的包，找到它们后删除前破折号，后用pip uninstall ip,pip uninstall yqt5卸载。
python3.9 换个版本试试，应该是这个版本不兼容。
warning是不用管的
