How to fix ModuleNotFoundError: No module named 'rest_auth' - docker

Question

I am using docker and pipenv for my virtual environment and I am getting the following error when I run docker-compose up:
ModuleNotFoundError: No module named 'rest_auth'
I tried pip install django-rest-auth and pipenv install django-rest-auth and also added the following to my INSTALLED_APPS
# Django REST Framework Apps
'rest_framework',
'rest_framework.authtoken',
'rest_auth',
INSTALLED_APPS = [
"django.contrib.admin",
"django.contrib.auth",
"django.contrib.contenttypes",
"django.contrib.sessions",
"django.contrib.messages",
"django.contrib.staticfiles",
# Other Package Apps
"storages",
# Django REST Framework Apps
'rest_framework',
'rest_framework.authtoken',
'rest_auth',
# Internal Apps
"authentication",
]
Expected to run docker container and access backend on localhost:8000
Actual: docker-compose up > ModuleNotFoundError: No module named 'rest_auth'

I had same error and did like this:
First I did:
pip uninstall django-rest_auth
then:
pip3 install django-rest_auth.
Hope this works.
