В учебном руководстве Django говорится, что я еще не установил установку DATABASE_ENGINE …, но я имею

Я работаю через учебное руководство Django и получаю следующую ошибку, когда я запускаю первоначальный Python manage.py syncdb:

Traceback (most recent call last):
File "manage.py", line 11, in <module>

django.core.exceptions.ImproperlyConfigured: You haven't set the DATABASE_ENGINE setting yet.

Мой settings.py похож:

DATABASES = {
  'default': {
    'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
    'NAME': 'dj_tut',                      # Or path to database file if using sqlite3.
    'USER': '',                      # Not used with sqlite3.
    'PASSWORD': '',                  # Not used with sqlite3.
    'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
    'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
  }
}

Я предполагаю, что это - что-то простое, но почему это не, видя установку ENGINE?
