ImproperlyConfigured:包含的 urlconf <project>.urls 中没有任何模式

我有一个在开发服务器上运行良好的 django (1.6.x) 项目，但在 Ubuntu 12.04.3 上的 Apache2 (2.2.22.1) 和 mod_wsgi (3.3-4) 下失败并出现错误

I have a django (1.6.x) project that runs fine with the dev server, but is failing under Apache2 (2.2.22.1) and mod_wsgi (3.3-4) on Ubuntu 12.04.3 with the error

ImproperlyConfigured: 包含的 urlconf erp.urls 中没有任何模式

ImproperlyConfigured: The included urlconf erp.urls doesn't have any patterns in it

我不明白为什么它适用于开发服务器而不适用于 Apache2/mod_wsgi，而且我发现很难追踪错误的来源.

I don't understand why it would work with the dev server but not Apache2/mod_wsgi and I'm finding it difficult to track down where the error is coming from.

还有许多其他类似的 SO 问题，但我使用 reverse 的唯一地方(之前发现的一个问题)是在我的模型中的 get_absolute_url 中 - 这应该没问题?

There are a number of other SO questions similar, but the only place I use reverse (one problem previously found) is in get_absolute_url in my models - this should be fine?

项目设置为la Two Scoops风格，具体布局为:

The project is set up a la Two Scoops style, in particular the layout is:
