It means it doesn't work with Ruby 1.9 yet. – Chapman

Answer 1

Execute Below command and its works

C:\Users\Steve>gem install ruby-debug --platform=mswin32

November

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? – Atombomb

The same, it installed correctly but Could not find ruby-debug-base (~> 0.10.4.0) amongst... when executing rdebug rake – Nazarene

paste here complete error stack, I will try to help to fix that problem – November

Do you have installed ruby-debug-base window version? – November

I too am getting the Could not find ruby-debug-base error. See here for the complete error. – Jellied

Answer 2

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

@Palani, the question was specific to Windows. – Overelaborate

Answer 4

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

gem install debugger

Answer 6

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

Gallenz

ruby-debug19 needs some headers and those headers are not available along with 1.9.2 – Churchwell

Palani Kannan: your comment is not accurate. ruby-debug19 gems requires Ruby source code which will be downloaded during the gem installation. – Gallenz

Answer 7

Also you can try this:

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