我有一个用Python 2.7.5编写的程序,我已经开始转移到我在WebFaction上托管的帐户。在那里,我想使用Pyramid 1.4 / Python 2.7实现它。我已经安装了所有软件包,但似乎我的Pyramid本身存在问题。我使用的软件包列表下面是我得到的错误。

md5, sys, os, tempfile, json, re, urllib2, time, multiprocessing requests

2013-10-18 21:37:48,821 ERROR [waitress][Dummy-1] Exception when serving /

有关如何调试此建议的任何建议吗?

答案 0 :(得分:0)

解决方案很简单,但并不那么明显。在view.py中我有一个返回的视图

Response(x)

其中 x 是我的多进程代码的输出,但它也是列表。这引起了一个问题。最后我去了 render_to_response 并将结果作为字典的一部分传递

return render_to_response('main.mak', {'results':x})
