在Flask中连接MySQL时出现ModuleNotFoundError: No module named 'MySQLdb'错误，只要在配置SQLALCHEMY_DATABASE_URI时，加上一个pymysql就可以了：
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql+pymysql://root:dzd123@localhost/你的数据库名' ，
当然，前提是要已经安装了pymysql，如果没有装pymysql，是会报ModuleNotFoundError: No module named 'pymysql'错误的，安装命令也很简单：pip install pymysql
