Почему Django пытается использовать MySQL вместо sqlite3

Question

Моя проблема заключается в следующем: при попытке выполнить миграцию выдается следующая ошибка:

python3 manage.py makemigrations
Traceback (most recent call last):
  File "/home/jenifer/.local/lib/python3.7/site-packages/django/db/backends/mysql/base.py", line 16, in <module>
    import MySQLdb as Database
ModuleNotFoundError: No module named 'MySQLdb'

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

Traceback (most recent call last):
  File "manage.py", line 21, in <module>
    main()
  File "manage.py", line 17, in main

Did you install mysqlclient?

Дело в том, что я никогда не говорил django использовать MySQL в Фактически, файл settings.py заявляет, что он должен использовать SQLite:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'gestlote.db'),
    }

}

Я уже пытался переустановить django, обновить его, установить pip3 pysqlite, но, похоже, ничего не работает. Пожалуйста, помогите мне
