python -m pip install mysql-connector-python-rf -i https://pypi.douban.com/simple/

报如下错

$ python -m pip install mysql-connector-python-rf

解决方式：先安装wheel

python -m pip install wheel -i https://pypi.douban.com/simple/

python -m pip install mysql-connector-python-rf -i https://pypi.douban.com/simple/

到此就安装成功了
