我有 RubyMine 版本 4.0.1，我将 Ruby 升级到 2.0.0。
尝试调试（开发或测试）时，我收到以下消息：
The gem ruby-debug-base required by the debugger is not currently installed. Would you like to install it?
单击“是”后，我收到此错误：

我读了这篇文章 - http://blog.jetbrains.com/ruby/2013/01/rubymine-enoki-eap-enjoy-ruby-2-0-apps-debugging/ 并尝试了 5.4 但同样的问题发生了。
