AttributeError：运行django-maintenancemode时，'module'对象没有属性'__all__'

Question

尝试在django中运行此中间件时遇到此错误。 https://github.com/shanx/django-maintenancemode

它正在返回

AttributeError: 'module' object has no attribute '__all__'.

我有什么问题吗？我试图在virtualenv中的本地主机环境中测试他的。我已将中间件放入设置文件中，无论我将模式设置为true还是false，都会返回此错误。我在我的模板文件夹中放置了一个503.html模板，我想让它服务。

你使用的是版本0.9.3，它是旧的，不受支持，并且与最新版本的Django相冲突。升级到0.10，你会得到一些有用的东西。

（The critical line现在修改the correct object; django.conf.urls.default no longer has __all__ defined）
