Python ERROR: Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

1.安装包的时候出现的问题

 

 2.试了好多方法，终于

pip3 install -r requirements.txt -i https://mirrors.aliyun.com/pypi/simple/ --ignore-installed

 

 

 安装成功
