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，我收到此消息：
The gem ruby-debug-base required by the debugger is not currently installed. Would you like to install it?
点击“是”后，我收到此错误：

我读过这篇文章 - 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。
答案 0 :(得分：4)
请更新到RubyMine 5.4.2，它将安装正确的调试gem版本。
5.x版本为Ruby 2.0安装以下gem：
ruby-debug-ide (0.4.17)
请注意，使用Ruby 2.0时，不需要linecache和ruby-debug-base宝石，RubyMine 5也不会安装这些宝石。
如果由于某种原因无法从RubyMine安装ruby-debug-ide gem，请尝试从终端安装：
gem install ruby-debug-ide
