服务器更改后的Flask无法正常工作

Question

在我编辑了服务器系统之后，我的flask应用程序就不能正常工作了。你知道吗

文件结构：

├── fcgi-bin
|   └── hubb.fcgi
├── hubb
│   ├── cms.py
│   ├── dbconnect.py
│   ├── hubb.py
│   ├── static
|   │   └── ...
|   └── templates
|       └── ...
└── hubb.tekkkz.com
    └── .htaccess

现在我的问题是，如果我使用redirect(url_for(...))，它会引发一个内部服务器错误，但是当我使用不带url的redirect时，如果使用真正的url，它就会工作。去hubb.tekkkz.com看看你自己

我的hubb.fcgi：

#!/usr/bin/env python2.7

import sys
sys.path.insert(0, "/var/www/virtual/tekkkz/hubb")

from flup.server.fcgi import WSGIServer
from hubb import app

if __name__ == '__main__':
    WSGIServer(app).run()

我的hubb.py：

#!/usr/bin/python2.7

那么，为什么会出现内部服务器错误呢？你知道吗
