Using Python 3.4.2
One app directory is missing a number of files, including __init__.py
This results in an error when trying to run any manage.py command.
It seems odd that the app directory is showing up multiple times in the
path, and that duplication seems to cause issues for Django.
Here is an example traceback:
(testenv)~/Development/testenv-dev/testenv$ python manage.py runserver
Traceback (most recent call last):
File "/Users/jessamyn/.virtualenvs/testenv/lib/python3.4/site-
packages/django/apps/config.py", line 100, in create
entry = module.default_app_config
AttributeError: 'module' object has no attribute 'default_app_config'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

configure this app with an AppConfig subclass with a 'path' class
attribute.
