Answer 1

You are using some weird debug gems, only the following are needed:

• ruby-debug-base19x
• ruby-debug-ide

First, remove all the ruby-debug* gems, then install the required gems using the following commands:

gem install ruby-debug-base19x --pre
gem install ruby-debug-ide --pre

You should get the following (or newer) versions:

ruby-debug-base19x (0.11.30.pre10)
ruby-debug-ide (0.4.17.beta9)

Adjust your Gemfile to include only these two gems (except the app specific gems).

If you are getting linecache19 related errors, install it as follows:

curl -OL http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem
gem install linecache19-0.5.13.gem

@Anjan has contributed the complete Gemfile changes for debugging:

gem 'linecache19', '>= 0.5.13', :git => 'https://github.com/robmathews/linecache19-0.5.13.git'
gem 'ruby-debug-base19x', '>= 0.11.30.pre10'
gem 'ruby-debug-ide', '>= 0.4.17.beta14'

Don't forget to update the bundle.
