Ruby on rails JRuby:Rake失败，出现Gem:：Version错误

我在对rake的任何调用中都会遇到以下错误。我正在使用安装了RVM的JRuby（1.5.1）上运行的Rails 3。我不认为总是这样，但我不知道如何找到它。我是否正确地认为这与我安装的gems有关（包括下面的清单）

---

shell将bin/rake脚本解释为Bash脚本，而不是Ruby脚本。您可以检查垃圾箱/耙顶部的shebang管线和/或重新安装耙。如果这无法解决问题，您可以像jruby-srake一样运行

$ rake metrics:all
/Users/Eric/.rvm/gems/jruby-1.5.1@backend/bin/rake: line 9: require: command not found
/Users/Eric/.rvm/gems/jruby-1.5.1@backend/bin/rake: line 11: version: command not found
