ERROR: Failed to build gem native extension on Mavericks

Question

I\'m attempting to run bundle in my Rails project on OSX 10.9. It fails when getting to the pg gem with this error:

Gem::Installer:         


        

Answer 1

An error occurred while installing debugger (1.6.5), and Bundler cannot continue. Make sure that `gem install debugger -v '1.6.5'` succeeds before bundling.

I was able to fix this error by rolling back to Ruby v2.0.0. I was running Ruby 2.1.1, which is not supported for this debugger version. Be sure to check your ruby version if you run into this issue as well.
