I can not make migration file

[soseki-angfa]

Subject: django 4.0/python 3.8

Problem

I can not create first migration. When I looked at error logs, It seems to me that django dose not recognise django-redshift-backend.

I have database setting as following.

Procedure to reproduce the problem

python3 manage.py makemigrations my_project

Error logs / results

django.core.exceptions.ImproperlyConfigured: 'django_redshift_backend' isn't an available database backend or couldn't be imported. Check the above exception. To use one of the built-in backends, use 'django.db.backends.XXX', where XXX is one of:
    'mysql', 'oracle', 'postgresql', 'sqlite3'

Expected results

Migration is created.

Environment info

• OS: Amazon Linux 2
• Python version: 3.8
• Django version: 4.0
• Django-Redshift-Backend version:3.0

Do you have any suggestion for this?

Regards.
