安装mysqlclient要先确认是否正确安装并配置好python，django，python对应的库文件python-dev
我自己安装的是python3.6
django2.0
pip install mysqlclient之后报错
看报错好像是gcc的问题，
sudo apt-get build-dep gcc 之后安装mysqlclient还是同样错误
尝试安装python3.6-dev
sudo apt-get install python3.6-dev
安装一半时候，下载超时
查看镜像设置
vim /etc/apt/sources.list

注掉原来的，替换上面的镜像地址进去
再次安装python3.6-dev，成功
安装mysqlclient 成功
