Django 1.9 Tutorial Part 2: No module named 'polls.apps' when running python manage.py makemigrations polls

Question

There are numerous similar questions here on SO, but they all seem to be for older versions, or are related to a typo.

In part 2 of the Django 1.9 tutorial, I am stuck at the initial migration for the polls app:

python manage.py makemigrations polls

When running this, I get the error: `ImportError: No module named 'polls.apps'

I am using Python 3.5.1 and Django 1.9.4

excerpt from mysite/settings.py

...
INSTALLED_APPS = [
    'polls.apps.PollsConfig',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

Answer 1

You are missing the apps.py file (and the polls.migrations package also) which should have been generated on this step: Creating the Polls app. Please review to ensure you've completed that step correctly.

Answer 2

What about if you replace

INSTALLED_APPS = [
    'polls.apps.PollsConfig',
    ...
]

by just

INSTALLED_APPS = [
    'polls',
    ...
]
