安装（和删除）Compass 后，我的 Rails 应用程序出现了一些问题。bundle install给了我以下内容：
/Users/[..]/.rvm/gems/ruby-1.9.2-head@rails3beta/gems/bundler 1.0.0.beta.2/lib/bundler/settings.rb:10:in `[]': undefined method `[]' for false:FalseClass (NoMethodError)

我试过清理 gemset 并重新安装 Bundler 和其他 gem，但没有运气。我也尝试过创建一个新的应用程序 - 捆绑程序在这里工作正常，所以我猜问题出在我的应用程序代码中，但我不知道去哪里找。
有任何想法吗？：-） 多谢你们。
