在OS X上调试Ruby 2.1调试

Question

I'm looking for a way to debug in ruby 2.1 on OSX. Specifically:

• Ruby 2.1.0
• Rails (3.2.recent)
• OS X 10.9.1

I'm looking for a recipe that will let me stop at breakpoints, step, next, etc. I've used the debugger gem in the past, ruby-debug, and also byebug. I'm having trouble getting any of 'em to build.

Anyone have a recipe that works? Thanks!

Answer 1

Working with pry is a great option when you want to debug.

Checkout the vid tutorial http://pryrepl.org/screencasts.html which showcases some of the features of it.

I generally use these gems for debugging:

group :development do
  gem 'pry'
  gem 'pry-nav'
  gem 'pry-rescue'
  gem 'pry-stack_explorer'
  gem 'pry-doc'
end

Hope it helps!

你也可以签出byebug ，它是版本> = 2.0的简单ruby调试器。
