ruby - 如何使用 Intellij 12.1.7 调试 Ruby 2.1.1p76

Question

如何使用 Intellij 12.1.7 调试 Ruby 2.1.1p76？我可以很好地运行我的脚本，但是当我单击调试按钮时，我会看到一个对话框:

The gem ruby-debug-base required by the debugger is not currently installed. Would you like to install it?

当我点击"is"时，我得到了这个:

10:36:21 AM Error running e2e

我知道我可以升级到 Intellij 13 来解决这个问题，但我不想这样做。

您可以使用 Ruby 远程调试。

1. 安装 rdebug-ide:

   gem install ruby-debug-ide --pre
   

2. 在 IDEA 中创建“Ruby 远程调试”配置

3. 从终端运行脚本:

   rdebug-ide --port 1234 --dispatcher-port 26162 -- yourscript.rb
   

4. 在IDEA中按“调试”
