Phusion Phusion Passenger preloader错误nginx

Question

我想提前感谢你帮我解决这个问题。我在这里发疯了，试图找出phusion passenger或我的rails应用程序出了什么问题。

我用谷歌搜索了很多东西，也读了https://github.com/phusion/passenger/wiki/Debugging-application-startup-problems上的所有内容，但我似乎还是搞不清楚问题出在哪里。

我已经列出了我认为问题所在，但可以在www.malikhandaan.com上访问完整的错误。

非常感谢你的帮助，提前。

(我是rails的新手，这是我第一次使用nginx部署应用程序)

经过一整晚的研究和插件，我发现ruby-2.0.0似乎有这个错误，因为我将ruby-1.9.3降级到了1.9.3，问题已经解决了……我从一个问题转移到了another...at，至少我已经超过了这个问题。:)

希望这对rails的新手有所帮助。
