title: error: App 'polls' could not be found. Is it in INSTALLED_APPS? *But polls is in INSTALLED_APPS in settings.py. I
body: <p>I am trying to create the 'polls' part of my Django project/website and the tutorial (<a href="https://docs.djangoproject.com/en/1.8/intro/tutorial01/" rel="noreferrer">https://docs.djangoproject.com/en/1.8/intro/tutorial01/</a>) says that before we 'activate' the models we have to include 'polls' in the INSTALLED_APPS library in settings.py. I did that, then I do--> $ python manage.py make migrations polls. This gives me the error--> App 'polls' could not be found. is it in INSTALLED_APPS?. What do I do from here?! I synced my database after I added polls, still doesn't work.</p>
