I can't get debugger installed to work in my ruby files. Can anyone see what the problem is?
I did 'require debugger' at the top of my file.rb and got this error when I ran ruby file.rb
rubygems/custom_require.rb:36:in `require': cannot load such file -- debugger (LoadError)
I did gem install debugger on my system but got this error message.
ERROR: Error installing debugger:
ERROR: Failed to build gem native extension.

necessary libraries and/or headers. Check the mkmf.log file for more

When I run gem environment, I get
