Migrations fail when `'django.contrib.sites'` is included in INSTALLED_APPS

Description (last modified by Andrew Conti)

When 'django.contrib.sites' is included in INSTALLED_APPS,

Running:

  python manage.py migrate

fails with:

    django.db.utils.ProgrammingError: relation "django_site" does not exist
    LINE 1: SELECT (1) AS "a" FROM "django_site" LIMIT 1

I have followed the docs and included SITE_ID = 1 in my settings.

Even more puzzling is that when I try to migrate the sites app separately with python manage.py migrate sites it that fails with:

CommandError: App 'sites' does not have migrations

This issue can be reporduced my cloning: https://github.com/agconti/django-contrib-sites-failed-migration-example and running the migrations.

Do you have any idea on way resolve this?

Installed Apps:

INSTALLED_APPS = ( 
 'django.contrib.admin',
  'django.contrib.sites',
  'django.contrib.auth',
  'django.contrib.contenttypes',
  'django.contrib.sessions',
  'django.contrib.messages',
  'django.contrib.staticfiles',
)

Migration error:

You have a custom entry in MIGRATION_MODULES for that app that points to a nonexistent module: 'sites': 'contrib.sites.migrations'.
