蟒蛇遷移（Django的）不與PostgreSQL的

Question

工作，我安裝了psycopg2，隨後安裝PostgreSQL時，在本教程以及Django文檔中給出的所有步驟：http://killtheyak.com/use-postgresql-with-django-flask/

但經營管理蟒當我得到這個例外。 py migrate

我想用戶所創建的位置：

sudo -u postgres createuser -s $USER 

不像用戶使用此：

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.postgresql_psycopg2', 
     'NAME': 'yournewdb', 
     'USER': 'yourusername', 
     'PASSWORD': 'yourpassword', 
     'HOST': 'localhost', 
     'PORT': '5432', 
    } 
}
