不能使用Django和MongoDB

Question

我得到django-nonrel，djangotoolbox并从GitHub mongodbengine和setting.py运行执行syncdb是如下：

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', 
) 

除了settings.py，我没有任何其他.py文件在我的项目。

我得到的错误是：

BaoxuShis-MacBook:ptl bxshi$ python manage.py syncdb

我觉得与这个错误有关mongodbengine，在BBS上谈论一个线程的东西，但它说，这已经是固定的。
