由于an issue in Sprockets that fails in Ruby 2.0,我需要将我的Rails版本更新到最新版本。结果,我的Gemfile看起来像这样:
gem 'rails', git: 'git://github.com/rails/rails.git', branch: "3-2-stable"
然后导致如下所示的堆栈跟踪。 Rails edge也显示了同样的问题,尽管他们正在针对Ruby 2.0运行他们的测试套件,所以它必须是兼容的。
所以我猜测可能存在依赖于Rails或Ruby构建的依赖库,这些库不能与Ruby 2.0-preview1一起使用

这是Bundler中的一个错误,如下所述:https://github.com/rails/rails/issues/8136
此后一直在修复。

我有这个问题。它是由gemspec(Prawn,在我的例子中)中的heredoc中的“this:”之类的心理观察引起的,并且认为它是一个哈希。我相信它在2.0.0-preview1中是一个回归,因为我之前有过ruby-head,并没有遇到过这个问题。
