Heroku在git push时无法编译应用（Python 2.7.3），推送被拒 - 可能是collectstatic问题

Question

我在Heroku上运行一个Python应用（版本2.7.3），但是在通过git推送代码时，部署失败了。

这是错误追踪信息：

 !     Heroku push rejected, failed to compile Python app

这是Heroku日志中相关的输出：

2013-02-12T15:18:45+00:00 heroku[slugc]: Slug compilation started
2013-02-12T15:18:54+00:00 heroku[slugc]: Slug compilation failed: failed to compile Python app

我觉得这可能跟python-dateutil这个库在Heroku上没有正确编译有关，而且collectstatic这个过程也失败了。这个问题是在我把这个库添加为依赖后才开始出现的。

其他在Stack Overflow上有类似输出的帖子似乎也遇到了同样的问题。它抱怨缺少time模块，这听起来有点奇怪，但可能这是个下游错误？

谢谢你们的任何建议！
