Django Heroku - ModuleNotFoundError: No module named 'django_heroku'

I had the same problem as well. I have psycopg2 installed. (for postgres)

Installing 'psycopg2- binary' solved my problem.

There was a problem with:

pip install django-heroku

It was not fully installed because thee was a problem with psycopg2 that was not installed. To install psycopg2, run:

pip install psycopg2

Then you can run pip install django-heroku and the error disappeared
