安装pymysql报错：

TypeError: ‘encoding‘ is an invalid keyword argument for this function

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in c:\users\lenovo\a
ppdata\local\temp\pip-install-ypbeoo\pymysql\

解决办法：

更新插件
python -m pip install --upgrade setupTools
python -m pip install --upgrade pip

速度过慢可修改为清华源：pip install -i https://pypi.tuna.tsinghua.edu.cn/simple

更新完成再次安装pymysql成功。
