Build Error installing with Ruby 2.0.0-p576 and Rails 3.2.21 (and rbenv)

[jackrg]

When doing "bundle update rails", I get the error listed below. Works okay if I change my gemfile to read "gem byebug, '~> 6.0'". Docs say that byebug 7.0 requires Ruby 2.0.0. Let me know if you need any more info.

My bad, rb_tracearg_event_flag was not public API in 2.0...

I'll fix this, but I'd strongly recommend you to upgrade your Ruby. The End Of Life of 2.0.0 is approaching and although byebug supports 2.0, it will behave weird in some cases. Given the high level of compatibility between ruby releases, I think the best one can do is upgrade.

Oh, I will, I just upgraded from 1.93 last week, and I’m waiting a week before moving to the latest 2.x version (I also upgraded from Rails 3.1 then as well). 4 years of technical debt … ;)
