使用django和python时出错

Question

mongodb的数据库设置

    DATABASES = {  
         'default': {  
            'ENGINE': 'django_mongodb_engine',  
            'NAME': 'test',  
            'USER': '',  
            'PASSWORD': '',  
            'HOST': 'localhost',  
            'PORT': '27017',  
            'SUPPORTS_TRANSACTIONS': False,  
        } 

安装了mongodb引擎，mongodb-norel，pymongo ..如果我遗漏任何东西，请指导我..
