Python Social Auth- import error when using Google Authentication

I successfully followed along this blog entry more than a month ago:http://www.artandlogic.com/blog/2014/04/tutorial-adding-facebooktwittergoogle-authentication-to-a-django-application/

When I created a new environment, and recreated the steps, I'm now getting an import error, no module named google_auth during template rendering.

It traces back to this line:

<a href="{% url 'social:begin' 'google-oauth2' %}?next={{ request.path }}">Login</a>

It looks like django is not looking in the social app for the correct template processing? Any ideas on why this is no longer working?

#settings.py
INSTALLED_APPS = (... , 'social.apps.django_app.default', ...)

AUTHENTICATION_BACKENDS = ('social.backends.google.GoogleOAuth2', 'django.contrib.auth.backends.ModelBackend')

TEMPLATE_CONTEXT_PROCESSORS = ('django.contrib.auth.context_processors.auth',
'django.core.context_processors.debug',
'django.core.context_processors.i18n',
'django.core.context_processors.media',
'django.core.context_processors.static',
'django.core.context_processors.tz',
'django.contrib.messages.context_processors.messages',
'social.apps.django_app.context_processors.backends',
'social.apps.django_app.context_processors.login_redirect')

#urls.py
urlpatterns = patterns('', 
url('', include('social.apps.django_app.urls', namespace='social')),
url('', include('django.contrib.auth.urls', namespace='auth')),
url(r'^$', 'app.views.home', name='home'),
)

If it is an option for you, I would propose to use django-allauth instead. I used both django-allauth and Python Social Auth and personally find it much easier to work with django-allauth. So if you have a chance, give it a try

This is one difficult problem.

The error, the first line of the stack trace gives a clue: "Traceback: .... wrapped_callback ...." The social.apps.django_app.views.auth view is called and is wrapped in decorator psa. This eventually produces the error but I think django.core.handlers.base.get_response is hiding the actual exception source. I think the reraise makes the stack trace incomplete at the moment.

The exception probably occurs in from social.backends.utils.get_backend. But it's hard to debug from a distance.

Can you comment out the try-catch around the line response = wrapped_callback(request, *callback_args, **callback_kwargs) in the file django.core.handlers.base. What is the new stack trace you get when loading the page?
