gem install ruby-debug-base19x -v 0.11.30.pre3
这是在我的开发机器上运行窗口7以及pik(见https://github.com/vertiginous/pik),devkit(参见https://github.com/oneclick/rubyinstaller/wiki/development-kit)和Ruby 1.9.3p0 / 1.9.2p290
以下是安装时您应该看到的示例：

虽然这对我来说是一个移动目标,因为我们正在使用预发行版本的gem来完成任务.最好留意发布.
另外要注意的是,在撰写本文时,当前的发行版是0.11.30.pre6,这不行,所以只做以下操作将失败：
gem install ruby-debug-base19x --pre
