I upgraded from Django 1.11 to Django 2.0.
When I ran 'makemigrations', I got this error.
{{{
File "/home/webapp/.virtualenvs/odin/lib/python3.5/site-
packages/django/db/migrations/questioner.py", line 51, in ask_initial
filenames = os.listdir(migrations_module.__path__[0])
TypeError: '_NamespacePath' object does not support indexing
}}}
I manage to fix it by editing the file
'django/db/migrations/questioner.py' line 51 from:
{{{
filenames = os.listdir(migrations_module.__path__[0])
}}}
to
{{{
filenames = os.listdir(list(migrations_module.__path__)[0])
}}}
I don't know if this is the correct solution.

Comment:
At least one of your migrations directories doesn't have an `__init__.py`
file. This is a regression in aadd3aeb2ba3153e35bd805c80c901f289a6f333 and
a recurrence of #21868 (which was committed without a test).
