how to fix this error: No module named 'allauth'?

Question

I want to use allauth in django API but when I installed it I got some errors I fixed it by django.setup() and after that, I get the error which tells me that I have to set DJANGO_SETTINGS_MODULE now I did that in manage.py:

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys
import django


def main():
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'website.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    os.environ['DJANGO_SETTINGS_MODULE'] = 'website.settings'
    django.setup()
    main()

but I get this Traceback:

Traceback (most recent call last):
  File "manage.py", line 23, in <module>
    django.setup()

  File "<frozen importlib._bootstrap>", line 991, in _find_and_load
  File "<frozen importlib._bootstrap>", line 973, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'allauth'

please can anyone tells me how can I fix that exception error? I did many searches but I get no help and I asked here but also I got no help so, please if anyone can help me!

Additional information:
that is what I did in settings.py after I installed allauth by pip3

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.sites',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'allauth',
    'allauth.account',
    'allauth.socialaccount',
    'allauth.account.auth_backends.AuthenticationBackend',
    'index.apps.IndexConfig',
    'account.apps.AccountConfig',
    'community.apps.CommunityConfig',
]

AUTHENTICATION_BACKENDS = (
    "django.contrib.auth.backends.ModelBackend",
    "allauth.account.auth_backends.AuthenticationBackend",
)

SITE_ID = 1

and in urls.py

path('accounts/', include('allauth.urls')),

Edit post:

by using virtualenv that Trace has raised:

Traceback (most recent call last):

Solution 1

By installing django-allauth as follows:

python -m pip install django-allauth

Solution 2

I solved my problem and the main problem was spin around allauth.account that I want to migrate it into INSTALLED_APPS also, I had an additional app in this case, 'allauth.account.auth_backends.AuthenticationBackend', those apps was the reason for the problems.
for the first app (allauth.account.auth_backends.AuthenticationBackend)I was getting an error that tells me that I am not able to migrate the INSTALLED_APPS without migrating allauth app first.
for the second app (allauth.account) I was getting an error duplicate 'account' because I have already application with that name so, I had to rename the app name which already exists to name like accounts for example until I can install allauth.account succeeded.
until I am able to specify one error of each app I was migrating each one separately to show the specific error to it but when I was migrating the both together I was getting that Traceback I specified above.

Are you using virtualenv? Is it activated?

[Abdelhamed Abdin]

Yes, I'm using virtualenv and it is activated

[Iain Shelvington]

Try running python -m pip install allauth when your virtualenv is active

[Abdelhamed Abdin]

I was run the code by Pycharm's command that I activate virtualenv into it and the above exception I typed it was raised because I was using Linux's terminal without run virtualenv so, now I have a new exception by Pycharm's command. I did edit the post you can see it now @Charnel

[Abdelhamed Abdin]

that doesn't work with me. could you show the edited post and show the new trace @IainShelvington

[Ryan]

This did not work for me
