在settings.py同级文件__init__.py中添加以下文件后

import pymysql
pymysql.install_as_MySQLdb()

执行python manage.py，报错“ModuleNotFoundError: No module named ‘MySQLdb‘”

底下提示"django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.Did you install mysqlclient?"

于是安装mysqlclient：“pip install mysqlclient”,报错：“ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.”

以下内容摘自：https://github.com/PyMySQL/mysqlclient-python

You may need to install the Python 3 and MySQL development headers and libraries like so:

• $ sudo apt-get install python3-dev default-libmysqlclient-dev build-essential # Debian / Ubuntu
• % sudo yum install python3-devel mysql-devel # Red Hat / CentOS

Then you can install mysqlclient via pip now:

$ pip install mysqlclient

 通过执行

```

　　sudo apt install libmysqlclient-dev

　　pip install mysqlclient

``

成功安装

然后执行"python manage.py migrate"成功

特别说明！！！

当你使用mysqlclient时，就不需要再在settings.py同级文件__init__.py中添加

```

　　import pymysql

　　pymysql.install_as_MySQLdb()

```

这串代码添加了会报错："django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3."

因为添加了，

会覆盖mysqlclient，血的教训！！！

五、Djiango初始使用时遇到的坑（No module named 'MySQLdb'）
