ruby-debug with Ruby 1.9.3?

Question

I just updated to Ruby 1.9.3p0 and Rails 3.1.1. Now when I try to launch the server, it complains that I should install ruby-debug, even though it\'s already in

Answer 1

Maybe not the definitive answer to this question, but I was lead here by a chain of closed duplicates.

For me the problem was that I run a project in both ruby 1.8 and ruby 1.9, and my Gemfile needed this change:

gem 'debugger', :require => 'ruby-debug', :platforms => :mri_19
gem 'ruby-debug', :platforms => :mri_18

Now it works for both rubies.

For Windows Users:

First Download :linecache19-0.5.13.gem and ruby-debug-base19-0.11.26.gem From : http://rubyforge.org/frs/?group_id=8883&release_id=46303

Assumption: Ruby is in c:\Ruby1.93

put the gem files downloaded to c:\temp (linecache19-0.5.13.gem and ruby-debug-base19-0.11.26.gem)

then execute from command line:

gem install c:\temp\linecache19-0.5.13.gem

gem install c:\temp\ruby-debug-base19-0.11.26.gem -- --with-ruby-include=C:\Ruby1.93\include\ruby-1.9.1\ruby-1.9.3-p0

Answer 4

See my answer here : Ruby-debug not working - Stack Overflow

It's about getting Ruby debugging to work with the following setup

• Mac OS X Lion 10.7.2
• Aptana Studio 3 (Build 3.0.8.201201201658)

• Using rvm, in my project working directory I have a .rvmrc stating:

  rvm use ruby-1.9.3-p0@mygemset
  

Basically, I had to use :

linecache19 (0.5.13)
ruby-debug-base19x (0.11.30.pre10)
ruby-debug-ide (0.4.16)

Note that I'm not using ruby-debug-base19 but ruby-debug-base19x

I hope this helps!

Answer 5

Also you need to check if the gem 'ruby_source_code' is already installed.

Check: http://bugs.ruby-lang.org/issues/1857#note-8

Answer 6

If you don't have rvm and assuming you ruby installation is in /usr/local/ruby-1.9.3-po your can use this command:

curl -L https://raw.github.com/gist/1533750 | sudo /bin/bash
