I am getting the same issue on ruby 1.9.3p194 installed via rbenv/ruby-build.

@Hydrozen You shouldn't if you upgrade debugger-ruby_core_source to 1.1.2

[cldwalker]

@tknazn debugger isn't supporting automated installs of candidate ruby versions. I guess I should make that more explicit in the readme.I suggest upgrading to a stable ruby i.e. ruby-1.9.3p194 or installing with the path to your ruby headers as described in the error message i.e. gem install debugger -- --with-ruby-include=YOUR_PATH

[cldwalker]

I've made the support of only official ruby releases more clear in the readme. If you have more to discuss here, feel free to and I can reopen.

I got this issue with Ruby-2.0.0-p481, installed through RVM.
I solved it by running
gem install debugger-ruby_core_source # the dependency was not satisfied
followed by
gem install debugger -v '1.6.6' -- --with-ruby-include=~/.rvm/rubies/ruby-2.0.0-p481/include # pointed to the include dir manually from the default ruby version from RVM
