不一定适用所有情况
ValueError: check_hostname requires server_hostname
WARNING: You are using pip version 21.1.1; however, version 21.1.2 is available.
You should consider upgrading via the 'C:\Python39\python.exe -m pip install --upgrade pip' command.
1.这样执行升级
C:\Python39\python.exe -m pip install --upgrade pip -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com
2.再安装对应的库
python -m pip install mitmproxy -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com
3.不一定解决所有情况
