django配置mysql中Error loading MySQLdb module: No module named 'MySQLdb'.

报错信息:
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named ‘MySQLdb’.
Did you install mysqlclient or MySQL-python?

解决方法:
项目根目录,或子应用上级,目录下__init__.py添加:
import pymysql
pymysql.install_as_MySQLdb()
