Debugger gem not supported in Ruby 2.1.0 / 2.1.1 / 2.1.2

Question

I just upgraded my RVM Ruby installation to version 2.1.0 and tried to bundle install when I got the following error:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension. Ruby version 2.1.0 is not supported. *** extconf.rb failed *** 

The error of course is self-explanatory, but I was wondering if there was a way to make the Debugger gem work with the latest release of Ruby?

Answer 1

Looks like version 1.6.5 adds support for Ruby 2.1.0. - Works as expected.

Update: Since Ruby 2.1.1 has been released version 1.6.8 of Debugger should be used.

Answer 2

This was mentioned in one of the comments, but I wanted to call attention to it:

byebug is the currently recommended debugger for Ruby 2.0+

This issue has been documented here, and cldwalker, the author of debugger, notes that debugger will be scoped to Ruby 1.9.2 and 1.9.3.
