Django - ImproperlyConfigured: Module "django.contrib.auth.middleware"
easy solution
just remove
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
from
MIDDLEWARE_CLASSES = (......)
in your project's settings.py
then, it should work!
I was getting the same error. But i had forgotten to get into my VirtualEnv BEFORE running my server.So make sure that from terminal you first activate virtualenv: source env/bin/activate
Then run: python manage.py runserver
As we can see in Django 1.8 release notes
django.contrib.auth.middleware.SessionAuthenticationMiddleware was added in Django 1.7.
And you are using Django-1.6.5
in your virtual environment, hence the does not define
error.
Probably you have a newer version of Django installed in your "normal" environment and the server runs correctly. To fix this upgrade Django version inside your virtual environment (prior to updating Django be sure to activate your virtual environment!)
Now to add my two cents to the answers, because everything until now was repetition from ZZY and user1776955
If you run pip install -U Django
you will probably bump your version to something higher than 1.10 and then the following will apply:
In Django 1.10, session verification will be enabled regardless of whether or not SessionAuthenticationMiddleware is enabled (at which point SessionAuthenticationMiddleware will have no significance)
Hence it will be safe to delete it and if you update past 2.0 you will HAVE to delete it because Django 2.0 release notes state that:
Also a bit unrelated but relevant when updating to this version is that
Support for old-style middleware using settings.MIDDLEWARE_CLASSES is removed
As far as my experience goes it is enough to change MIDDLEWARE_CLASSES
to just MIDDLEWARE
and delete 'django.contrib.auth.middleware.SessionAuthenticationMiddleware'
from the list.
