ModuleNotFoundError: No module named 'registration'

Question

I have an issue with Django-Registration. The package is properly installed, however when I run python3.6 manage.py runserver, I get the following error :

ModuleNotFoundError: No module named 'registration'

The screenshot of my Settings.py, Urls.py, and HTML Template file is attached below: [enter image description here][1]

Answer 1

From the docs:

Prior to 3.x, django-registration installed a Python module named registration. To avoid silent incompatibilities, and to conform to more recent best practices, django-registration 3.x now installs a module named django_registration. Attempts to import from the registration module will immediately fail with ImportError.

Answer 2

I found the solution.

Turns out the app is able to serve successfully when you install :

pip install django-registration==2.4.1 

instead of

pip install django-registration

The latest django-registration version is 3.0 but 2.4.1 works. Just make sure to uninstall any prior version of django-registration, and then update your project with pip freeze > requirements.txt .

Thanks!
