debugger doesn't work with Ruby 2.0.0+

[caseywatts]

In ruby version 2.0.0+ bundle install fails.

It's because we're using Jazz Hands which brings in Pry Debugger, and pry-debugger doesn't work with Ruby 2.0.0+ https://github.com/nixme/jazz_hands https://github.com/nixme/pry-debugger

We might be able to switch to Pry Byebug? https://github.com/deivid-rodriguez/pry-byebug

Let's just disable jazz hands for now and replace it with vanilla gem 'pry'

Gem::InstallError: byebug requires Ruby version >= 2.0.0. An error occurred while installing byebug (2.7.0), and Bundler cannot continue. Make sure that gem install byebug -v '2.7.0' succeeds before bundling.

Made separate Gemfile lines, targeted at different ruby versions:

gem 'jazz_hands', platform: [:ruby_19]
gem 'pry-byebug', platform: [:ruby_20]

Good call with pry-byebug - we're going to want to migrate all of our projects to byebug/pry-byebug since debugger is no longer maintained.

Commenting out gem 'jazz_hands' and adding gem 'pry-byebug' got it to finish the bundle install for me.

@dgoerger I think the two-liner above is useful for compatibility into the future - especially if the user can use different Ruby versions. Some people like to create different Gemfiles for different ruby versions, but that seems like too much of a hassle to me. :information_desk_person:

[jasonkliu]

Ok I think I was wrong @dgoerger the two-liner doesn't work at the moment... that needs fixing..

This and #288 will have to wait until I get back on my main machine ~approx 2 weeks
