我正在从 1.4 升级到 Django 1.8。升级后运行服务器在没有我的应用程序的情况下工作正常。但是当我将其中之一添加到 installed_apps 时，它只是在启动时挂起。 命令:
C:\Programs\Python27\python.exe C:/Projects/prj/django/django_projects/manage.py runserver localhost:8080 --verbosity=3
并且没有提供输出(即使我使用 verbosity=3)。 这是为 python.exe http://clip2net.com/s/3pQPHSb 设置的 procmon 的屏幕截图 有什么方法可以调试挂起的原因吗？

请您参考如下方法:
显然，这些版本之间发生了很多变化，因此我怀疑是否需要进行简单的更改。以下是一些简化升级路径的建议:
尝试使用中间版本运行您的应用，看看它何时开始挂起。这可能会为您提供有关需要更改的内容的线索。此外，您应该在增加版本时开始收到弃用警告。
尝试
runserver_plus来自django-extensions以获得更多反馈。看看this post关于从 1.4 升级到 1.7。
Here是来自 the Open edX group 的一些广泛注释目前正在将多个应用程序从 1.4 升级到 1.8。
