【问题描述】：
我的最终目标是在新服务器上部署 Django 应用程序，而我所拥有的只是旧服务器磁盘的原始映像。我已经在新服务器上设置了所有内容：uwsgi、python、mysql、django 等。但是让我们来解决我的问题：当我运行时
uwsgi --http :8001 --module propotolki.wsgi
它运行没有错误，但是当我尝试通过浏览器访问它时，我在日志中得到以下堆栈跟踪：
Internal Server Error: /

这是我从 mysql 控制台得到的，证明表 确实 存在：

我远不是 Django 专家，所以请询问任何需要的信息。
我也尝试过python manager.py syncdb，但我收到类似的错误提示其他表也不存在：
