Can't install ruby-debug-base19x gem

Question

When I try to install ruby-debug-base19x gem for debug my application using the RubyMine IDE I received the below error message, can anybody help me?

I\'m using Mac

Answer 1

You can try

gem install ruby-debug-ide19

(according to the wiki). This installs for me on OS X 10.7.4, but you may want to give the debugger gem a shot (gem install debugger). It's actually maintained, unlike most of the ruby-debug* gems.
