I haven’t yet gotten Komodo IDE 12.0.1 working with Ruby debugging using byebug. I’ve gotten close by using byebug v 9.1.0 as Careh suggested in a separate thread. (my os = Linux Mint 20.0 and Ruby version manager RVM)
If you have Komodo IDE debugging working with any OS and any Ruby version I, and probably others, would love to hear the details.
I can confirm that using Komodo IDE 12.0.1 debugging with Ruby 2.4.1, gem byebug 9.0.1 works as expected.
