django-admin runserver抛出错误

Question

我已经安装了

• 的Django == 1.10.0
• pymongo == 2.7.1
• MongoDB 2.6
• 的Python == 2.7
• 6 == 1.10.0
• MongoDB 2.6
• mongoengine == 0.9.0

在mysite/mysite/settings.py我添加了

# Database
# https://docs.djangoproject.com/en/1.10/ref/settings/#databases
DATABASES = {
    'default': {
        #'ENGINE': 'django_mongodb_engine',
    'ENGINE': 'django.db.backends.dummy',
        'NAME': 'test',
        'USER': 'admin',
        'PASSWORD': 'smmis@123#',
            }
}

#start
AUTHENTICATION_BACKENDS = (
    'mongoengine.django.auth.MongoEngineBackend',
)
from mongoengine import *
    connect('test')
   # connect('test', host='mongodb://127.0.0.1',  port=50226)
#end

当我运行django-admin runserver时会抛出错误

尽管SECRET_KEY = '9&q3vm=wpl3&r_8vgqch3*$+h*kp+urol&z=!gk*79lhwvjx'位于mysite/settings.py

我错过了什么我是Django的新手

django-admin默认情况下不设置您要使用的设置文件。

您可以django-admin runserver --settings=mysite.settings或者您可以使用python manage.py runserver（manage.py将设置文件设置为其帮助程序功能的一部分）。

或者，我实际上更喜欢使用django-admin，但后来我使用名为direnv（https://direnv.net/）的lib在我的项目文件夹的上下文中设置DJANGO_SETTINGS_MODULE环境变量。
