引言

最近发现了一款比较厉害的script，能够下载好多网站上的音乐，虽然文档上说也可以下载视频，emm，没有试过，咳咳，言归正传，我在运行pip安装第三方库的时候，总是爆出警告，虽然用着没有什么影响吧，但是强迫症的我感觉很烦躁。后来呢想pip好久没更新了，更新也出了问题。。。

解决方案

找到python路径，删除提示的那些损坏的包
例如我的是：D:\Software\Microsoft Visual Studio\Shared\Python37_64\Lib\site-packages
进去之后有一些"~"前缀的文件夹，干掉就好了。

过程

1. 关闭所有的python文件

2. pip更新，当时的终端给关了，没有存留记录，更新之后下载可以下载但是诡异的是卸载后拒绝访问，大概是提示的这样子的错误，然后pip就不能用了。尬。

3. 离线安装pip，稀里糊涂的各种install，最后也就好了，仿佛遇到了玄学问题
