migrations error

[bluebamus]

I found in a migrations error.
my error case is that
"/www/django-pinax-forums/django_pinax_forums/django_pinax_forums/settings.py", line 2, in
import dj_database_url"

I just make a django new project, and doing following your step.

I'm refer to "https://pinaxproject.com/pinax/quick_start/"
using django latest version, python 3.9,
and input command as "django-admin startproject --template=https://github.com/pinax/pinax-starter-projects/zipball/account django_pinax_forums"
after above step, doing 'python manage.py makemigrations' then showing ' import dj_database_url' error

I don't know whether it is. If not, let me know how I can.
