I'm having trouble installing the Ruby-Debug Gem on windows. What does this error mean? How can I fix this? Thanks 

C:\Users\Steve>gem install ruby-debug

  • I tried this but when I try to run my server in debug mode it says it can't find `ruby-debug-base`, even though it's on my gems list and listed in my Gemfile. Any ideas? – Samo Apr 06 '11 at 16:28
  • The same, it installed correctly but `Could not find ruby-debug-base (~> 0.10.4.0) amongst...` when executing `rdebug rake` – Jaime Hablutzel Apr 18 '12 at 20:40
  • paste here complete error stack, I will try to help to fix that problem – AMIC MING Apr 19 '12 at 16:23

  • Do you have installed ruby-debug-base window version? – AMIC MING Aug 15 '12 at 23:25
  • I too am getting the `Could not find ruby-debug-base` error. See [here](http://pastebin.com/nBM3LaJE) for the complete error. – Jeff Axelrod Oct 16 '12 at 17:19

I ran into the same problem. Following steps should get you through:

  1. Install ruby using RubyInstaller
  2. Install devkit

  3. Install ruby-debug19 instead of ruby-debug.

    gem install ruby-debug19

this port of ruby-debug that works on 1.9.2 and 1.9.3 worked for me. Just type

gem install debugger

Also you can try this:

gem install ruby-debug-ide --platform=ruby --pre

I found this answer worked easiest for me: http://github.com/oneclick/rubyinstaller/wiki/development-kit

The error seems clear:

Can't handle 1.9.x yet

*** extconf.rb failed ***

You're trying to install ruby-debug gem, which is compatible only with Ruby 1.8.x on Ruby 1.9.x

Please install ruby-debug19, which is compatible with Ruby 1.9.x

gem install ruby-debug19
