最近打算使用aiohttp做一些实验，但是发现aiohttp一直装不上，安装报错

ERROR: Failed building wheel for aiohttp
Failed to build aiohttp
ERROR: Could not build wheels for aiohttp, which is required to install pyproject.toml-based projects
对于这个错误显示的Microsoft Visual Studio工具相关错误，怀疑为之前重装过不同的python版本导致，最后重新装了一个python3.9.8版本，路径直接放D盘下面，之后输入python --version查看版本之后，出现为空
环境变量又配置了python39的路径，在官网下载之后的文件夹默认命名为Python+版本号，安装前勾选添加到环境变量，因此环境变量如下
以前安装的文件名为python，把文件名python39改成了python之后就能显示版本号了，环境变量如上图所示没有改动，这里一度怀疑是有缓存没有清除（希望知道原因的大佬解释一下）
之后使用pip命令查看内容，出现错误
Fatal error in launcher: Unable to create process using '"D:\python39\python.exe" "D:\python\Scripts\pip.exe" ': ???????????
此时使用python -m pip install --upgrade pip进行pip更新又出现以下报错

最后通过查一下资料，发现需要将旧的pip源文件进行删除，有两个位置需要清楚，具体路径为python/Lib/site-packages/pip-xx.xx.xx.dist-info，由于python版本不同，此处版本号不一定一样
另一处路径如下python/Scripts/，所有pip开头的文件
最后一步进行安装
python -m pip install --upgrade pip
重装完成之后正常使用
使用pycharm安装aiohttp库也成功了，如果用命令行方式使用
pip install aiohttp
