How can I remove all the gems installed using bundle install in a particular RoR project. I don't want to uninstall gems that are used by other projects.

Since we're using ruby you could do something like this I guess:

bundle list | ruby -e 'ARGF.readlines[1..-1].each {|l| g = l.split(" ");  puts "Removing #{g[1]}"; `gem uninstall --force #{g[1]} -v #{g[2].gsub(/\(|\)/, "")}`; }'

NOTE: Only lightly tested.
