Ruby on Rails: debugging rake tasks
I found the solution.
$ gem install ruby-debug$ ruby-debug rake my:taskor on some systems
$ rdebug rake my:task
Andrey Kouznetsov's answer didn't work for me using Ruby 1.9.3. The ruby-debug gem doesn't seem to support Ruby 1.9. I had to use the debugger gem: https://github.com/cldwalker/debugger.
- Add
gem 'debugger'to my Gemfile's development group. - Run
bundle. - Add
require 'debugger'to the top of my rake task. - Add a call to
debuggerwhere I wanted a breakpoint in my rake task. - Run the rake task normally from the command line, e.g.:
rake my:task.
I highly recommend pry for this
bundle install pryrequire 'pry'rake ...In your rake task file:
binding.pry
