耙和未初始化的常数
我花了几天时间试图解决这个问题。
Rake抛出以下错误：
dcarpenter$ rake rake aborted! uninitialized constant ActionView::Helpers::JavaScriptProxy 我似乎无法找到任何在Google，本网站或其他地方遇到此问题的人。 我应该采取哪些步骤来解决这个问题以及我需要知道什么？

仅仅是为了说，jrails并没有因为Rails 3而受到抱怨，而且该项目自2009年以来基本上已经死了。如果你使用的是Rails 3，你应该使用jquery-ujsgem，这种gem可以填充进入的洞穴。
这并不意味着它只会起作用，但这是你真正想要转向Rails 3的第一步。
