Django-notifications won't sync

Question

I'm trying to set up django-notifications in my app. I'm following the instructions to install it, which are pretty straight-forward: https://github.com/brantyoung/django-notifications#installation

When I run manage.py migrate notifications I get:

django.db.utils.ProgrammingError: (1146, "Table '{{database}}.notifications_notification' doesn't exist")

I'm at a loss.

Traceback (most recent call last):

You forget to run syncdb before migrating data. The table doesn't exists because it's syncdb that created it, not the migration.

Reference: http://south.readthedocs.org/en/latest/tutorial/part1.html

(If this fails complaining that south_migrationhistory does not exist, you forgot to run syncdb after you installed South.)
