I am using Ultimate 2018.3 and have the Ruby plugin installed and enabled. Running on OSX High Sierra
I have also install RVM version 1.29.7 and have installed the latest version of ruby though that, being v2.6.0p0
My reading of the documentation is that I should be able to see that Ruby automatically in my SDK list with Project Settings. I don't. I've tried to add it directly by adding a new SDK and pointing it at the ruby directory within the .rvm folder but that is just not recognised.
Am i not configuring something correctly or is this not supported by Intellij anymore?
