1. Debugger Installation

Install Ruby Dependencies

Debugging in this extension implements the ruby debug ide protocol to allow VS Code to communicate with ruby debug, it requires ruby-debug-ide to be installed on your machine. This is also how RubyMine/NetBeans implement debugging by default.

• If you are using JRuby or Ruby v1.8.x (jruby, ruby_18, mingw_18)
  • gem install ruby-debug-ide, the latest version is 0.6.0. Make sure ruby-debug-base is installed together with ruby-debug-ide.
• If you are using Ruby v1.9.x (ruby_19, mingw_19)
  • gem install ruby-debug-ide, the latest version is 0.6.0. Make sure ruby-debug-base19x is installed together with ruby-debug-ide.
• If you are using Ruby v2.x
  • gem install ruby-debug-ide -v 0.6.0 or higher versions
  • gem install debase -v 0.2.1 or higher versions

Add VS Code config to your project

Go to the debugger view of VS Code and hit the gear icon. Choose Ruby or Ruby Debugger from the prompt window, then you'll get the sample launch config in .vscode/launch.json
