dev_appserver.py not starting development server

I've been following this tutorial here in an attempt to build an app on Google app engine:

https://github.com/GoogleCloudPlatform/appengine-django-skeleton

I've hit a brick wall though in that when I run dev_appserver.py, 2 out of 3 servers run fine. But the development server just returns 500 errors.

The exact console output is the following:

ubuntu@ubuntu:~/Desktop/appengine-django-skeleton$ dev_appserver.py --port=9999 app.yaml

    "'%s' isn't a subclass of AppConfig." % entry)
ImproperlyConfigured: 'django.contrib.admin.apps.AdminConfig' isn't a subclass of AppConfig.

And I'm guessing that the key line here is

ImproperlyConfigured: 'django.contrib.admin.apps.AdminConfig' isn't a subclass of AppConfig.

No code changes have been made to the file from github. Only the configuration changes listed on the github page.

I have manged to solve this problem by installing all the modules required on virtualenv not inside the lib directory. After cloning the repository, run this command.

pip install -r requirements.txt
