无法运行我的Django应用服务器
我无法启动我的Django应用的服务器。下面是自从上次成功运行以来发生的一些事情：
我的电脑出现了一些问题，所以我把项目保存在一个服务器上，并在服务器上工作了两周，确保我可以顺利开发（一开始一切都很好）。然后我把电脑格式化了，所以又重新安装了一切。
当我尝试运行python manage.py runserver命令时，它让我安装我需求文件中的所有内容。我照做了。
现在所有的需求都安装好了（或者我认为是这样），但是在运行命令时，我得到了以下信息：
（是的，我试过 syncdb）
$ python manage.py runserver
Traceback (most recent call last):

有什么想法吗？？
谢谢
