一、问题:
今天不知道怎么了,我使用pip安装各种模块,都报错,始终没有解决,没有办法,把pip重新卸载安装了好几个版本,还是不行。
现在这个是最后一个pip版本的报错,实在弄了太久了,找到一个python安装解压包安装的方法。

二、几个小点
每次找,太麻烦,我把我今天卸载安装pip的方法记下来吧。有需要也可以参考参考。
1、windows卸载pip
python -m pip uninstall pip
我卸载之后发现,python安装目录下的Scripts目录中还有残留,决定彻底删除测试。
我的安装目录 D:\python_work_tools\python3.6.8\Scripts
2、更新pip
python -m pip install --upgrade pip
3、安装pip
找到自己想安装的pip版本:
我安装的地址:https://pypi.org/project/pip/19.2/
中间的 Release history
是pip的所以版本,也可以自己选择。
点击Download files
下载,下载gz的模块压缩包。
然后解压。进入解压目录。
然后cmd或者powershell进入解压目录,
python setup.py install
三、解决其他模块的安装问题:
我也不知道,我的公司电脑突然怎么了,今天突然安装不了模块了。然后根据上面安装pip的步骤,觉得其他的模块看也可以,结果安装就成功了。
这个步骤我就不截图了,根据上面的安装pip的步骤,安装其他模块即可。
感觉一时半会也不好了,先将就这使用下载gz的压缩包安装模块吧。
