Rake 和未初始化的常量

Question

我已经花了好几个小时试图解决这个问题。

Rake 抛出以下错误：

dcarpenter$ rake

    rake aborted!
    uninitialized constant ActionView::Helpers::JavaScriptProxy

我似乎无法在 Google、此站点或其他地方找到遇到此问题的任何人。 我应该采取什么步骤来解决这个问题，我需要知道什么？

只是为了说明，jrails 与 Rails 3 不兼容，并且该项目自 2009 年以来基本上已经死了。如果你在 Rails 3 上，你应该使用 jquery-ujs gem 来填补 jrails 过去的漏洞进入。

这并不意味着它会正常工作，但这是您真正想要迁移到 Rails 3 的第一步。
