如何调试opscode chef/ruby​​错误？

Question

我是一个蟒蛇小子，正在努力理解ruby stacktraces。如果有人能够告诉我一个系统的方法来深入了解导致这样的信息的底线，我会很感激。运行Opscode 11.4。我认为它可能是由于过时的opscode食谱，所以更新柜0.017 - 最新的。但问题依然存在。我想也许这是另一本食谱的依赖。这是elasticsearch，但没有指定版本。在任何情况下，这种方法看起来都像猜测一样，但是并没有一个明确的堆栈轨迹来显示底层问题。行动这种讯息的正确方法是什么？

看来，社区网站的版本0.0.17是不一样的，即使它们具有相同的版本号，目前的头。从github https://github.com/opscode-cookbooks/ark/commit/b8c4aaf17d6e88aa857af6b2038eb0dba9981c0b安装源码解决了这个问题。
