让 pubsubhubbub 中心正常运行

Question

我已按照 http://code.google.com/p/pubsubhubbub 中的说明进行操作/wiki/DeveloperGettingStartedGuide 设置中心。 当我启动集线器时，我收到以下警告

$ sudo python2.5 google_appengine/dev_appserver.py pubsubhubbub/hub/

当我将浏览器指向http://localhost:8080 我得到了一个令人讨厌的异常。在我的浏览器中抛出了 AttributeError 。 console

作为Python新手需要帮助，有什么想法吗？

该教程位于 http://code.google.com/p/pubsubhubbub/wiki/DeveloperGettingStartedGuide 已过时，您需要使用 至少 google app engine 1.2.8 才能使其正常工作（其中添加了新的 memcache offset_multi 方法以及 incr 和 decr 中的批量支持）
