deepin/ubuntu下安装mysqlclient ERROR: Command errored out with exit status 1: python setup.py egg_info

这是因为缺少libmysqlclient-dev依赖，如果直接安装libmysqlclient-dev会报错

sudo apt-get install libmysqlclient-dev
E: 软件包 libmysqlclient-dev 没有可安装候选

解决办法：

sudo apt-get install default-libmysqlclient-dev

pip install mysqlclient
