ModuleNotFoundError: No module named ‘MySQLdb’

When running migration for a Django application with “python manage.py migrate”, I got the following error message

ModuleNotFoundError: No module named 'MySQLdb'

To fix install

pip install mysqlclient

This will require MySQL development package. On the Ubuntu server running MariaDB, I installed packaged libmariadb-dev

sudo apt install libmariadb-dev
