Json Dreamhost上的乘客运行烧瓶站点返回500错误

我很难让乘客和Flask一起工作。我在运行Python 3.5.2的virutalenv中运行DreamHost上的Flask站点。应用程序应该从URL中的查询字符串接收输入，解析服务器端JSON文件，在JSON文件中搜索所述查询字符串，重新格式化JSON，然后将其发送回客户端。相反，它给了我500个错误代码。这是我的密码。请原谅所有的日志函数调用。我已经尽我所能四处搜索了

这是我的.htaccess：

</VirtualHost>

编辑2：我使用粘贴Python模块从Flask收集错误，它给了我以下信息：

File '/home/dh_user/.pyenv/versions/3.5.2/envs/flask/lib/python3.5/site-packages/paste/exceptions/errormiddleware.py', line 224 in next
  return self.app_iterator.next()
AttributeError: 'ClosingIterator' object has no attribute 'next'

---

嗯，我好像已经修好了。我记得我做的是删除粘贴，然后再做一些事情。

请发送回溯。
