在linux上安装 mysqlclint 的时候使用：
pip install mysqlclient
但是报错：
[root@localhost ~]# pip install mysqlclient DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

于是百度后，需要安装相关依赖 mysql-devel：
yum install mysql-devel
完成后，再执行 pip install mysqlclient 还有报错，报错信息变了，好兆头：

百度后，继续安装依赖 python-devel ：
yum install python-devel
然后再安装：
