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

這是因爲缺少libmysqlclient-dev依賴，如果直接安裝libmysqlclient-dev會報錯

sudo apt-get install libmysqlclient-dev
E: 軟件包 libmysqlclient-dev 沒有可安裝候選

解決辦法：

sudo apt-get install default-libmysqlclient-dev

pip install mysqlclient
