Can not run syncdb with Django and mongoDB - django

Question

I get django-nonrel, djangotoolbox and mongodbengine from github, and the setting.py is as following:
DATABASES = {
'default': {
'ENGINE': 'django_mongodb_engine', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'admin', # 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.
}
}
MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
)
ROOT_URLCONF = 'ptl.urls'
TEMPLATE_DIRS = ('/Users/bxshi/PycharmProjects/ptl/templates',)
INSTALLED_APPS = (
'django.contrib.contenttypes',
'django.contrib.sessions',
)
Except that settings.py, I do not have any other .py file in my project.
The error I got is that:
BaoxuShis-MacBook:ptl bxshi$ python manage.py syncdb

I find something related to this error about mongodbengine, a thread on BBS talk about that, but it says this is already fixed.

Simply use the official installation instructions on https://django-mongodb-engine.readthedocs.org/en/latest/topics/setup.html
