如何在Django Framework和Python3中使用MongoDB

Question

我是python，django和mongoDB世界的新手。我設置的Django項目（VIRTUALENV，Python3，Django的== 1.10.1的MongoDB），並安裝了一些基本的程序包要求：

Django==1.10.1 
django-mongodb-engine==0.6.0 
djangotoolbox==1.8.0 
mongoengine==0.9.0 
pymongo==3.3.0 

但是當我試圖用python3 manage.py syncdb來執行syncdb，那麼它顯示

~/virtenv/lib/python3.5/site-packages/django_mongodb_engine/base.py", line 272 
    raise ImproperlyConfigured, exc_info[1], exc_info[2] 
          ^
SyntaxError: invalid syntax

從文檔django-mongodb-engine

DATABASES = { 
    'default' : { 
     'ENGINE' : 'django_mongodb_engine', 
     'NAME' : 'my_database' 
    } 
}
