NotperlyConfigured：settings.DATABASES配置不正确。请提供ENGINE值

自从过去3天以来，我一直在遭遇这个问题。

我已经在不同的博客（甚至是stackoverflow）和解决方案上看到了重复票的音调，但是没有一个在我身上发挥作用。

最后我别无选择，只能在我的settings.py中询问这里有什么问题，为什么即使在新的AWS实例上移动django应用程序后问题仍未解决。

我的setting.py：

最近我的项目在Django 1.4上运行，但由于一些smartbyte编码错误，我更新到1.5。在那个问题开始后我降级到Django 1.4。它甚至在降级之后都没有进行，然后我将整个项目转移到新的AWS实例（ubuntu 14.04）。

我正在使用Django 1.5 python2.7

settings.configure()

似乎凌驾于私密环境之上。这一定是您问题的关键。

事实上，如果你在没有任何参数的情况下调用configure（），django将使用默认设置，通常没有在其中定义任何数据库引擎，因此你会得到错误。
