One of RubyMine’s strongest features is its debugging tool. But it’s always been finicky to get it working for me. I finally got it to work since upgrading to Ruby 2.1.x. The situation was complicated by Ruby 2.x not yet supported by debugger gem… etc.
To get everything to sing in harmony, here’s what I used:
byebug(in place ofdebugger)ruby-debug-idegem (RubyMine requirement)debasegem (RubyMine requirement)
And that was it!
