Answer 1

I had a different problem which prevented me from installing ruby-debug-base19x but resulted in different specific errors than danilodeveloper got. Mentioning it here since those who have my problem will probably find this question first:

RubyMine 5.4.3.2.1 [love that version number] installed a version of the debugger-ruby_core_source gem (1.1.9) which was too old for the ruby-debug-base19x it wanted (0.11.30.pre12) and/or the ruby I'm using (1.9.3-p484). The solution was to

gem update debugger-ruby_core_source

(bringing it to 1.3.2) and let RubyMine try to install ruby-debug-base19x again, which succeeded.
