$ irb
irb(main):001:0> require 'ruby-debug'
=> true

This didn't work for me on my Mac OSX, it worked on my Ubuntu box, any ideas?

@mdoroudi comment out ruby-debug , use pry . I think that is the best solution.

@prabeshshrestha I'm not so familiar with pry is it (https://github.com/pry/pry) ? because it sais it's a replacement for irb, but I'm looking to debug my program in rails

@mdoroudi I am using it to debug my applications in rails . It works great with rails application. Let me know if you are still not able to use it for your rails app.
