django配置文件settings.py里面配置数据库连接 Error loading MySQLdb module错误

1、在 untitled1108/ untiled1108/ settings.py里面配置数据库

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': "test",
        "USER": "root",
        "PASSWORD": "123456",
        "HOST": "127.0.0.1",
        "PORT" : "3306" ,
    }
}

2、执行python manage.py makemigrations报错

E:\pycharmWorkspace\untitled1108>python manage.py makemigrations
Traceback (most recent call last):
  File "E:\Program Files\python3.6\lib\site-packages\django-2.0.13-py3.6.egg\dja
ngo\db\backends\mysql\base.py", line 15, in <module>
    import MySQLdb as Database
ModuleNotFoundError: No module named 'MySQLdb'

The above exception was the direct cause of the following exception:

    ) from err
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?

提示没有安装mysql db，实际已经安装了pymsql

3、解决办法，在 untitled1108/ untitled1108/ __init__.py里面设置如下

import pymysql
pymysql.install_as_MySQLdb()

配置后再执行就正常了

E:\pycharmWorkspace\untitled1108>python manage.py makemigrations
