AttributeError: 'Settings' object has no attribute 'DATABASE_ENGINE'

[ningyougang]

环境：Centos、python2.7.7 Django:1.7 south:0.7
settings.py 里的部分配置：
INSTALLED_APPS = (
'south',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'polls'
)
其中south:为同步模型到数据库的第三方模块，用来取代syncdb。
polls:为自己的投票应用。
目前我执行python manage.py syncdb或者python manage.py startmigration polls --initial均报错，报错信息如下：

在settings文件里 DATABASES----default中把DATABASE_ENGINE换成ENGINE，应该就能搞定了。版本不一致的吧？不知道你是哪个版本的demo
