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

Why

The reason of this issue is because you didn’t install MySQL-python for Django to connect to MySQL DB.

Or you didn’t install them in your virtualenv.

Solution

First switch to root when you are using virtualenv.
Then install the following packages by

pip install pymysql
pip install MySQL-python

Finally exit root user and install packages above again in your virtualenv.

Then you will see that your server can be run successfully.
