I have come to the conclusion that 3.0.1 was much better than 3.1 when it comes to rvm, ruby upgrade through rvm, various gemsets etc.
At this point, I am considering that I should just continue to use 3.0.1 and upgrade to a newer version that fixes 3.1 woes. I find it extremely annoying to open a simple project in RM 3.1 when I have a more-or-less straightforward Gemfile.
First off, it (the ruby interpreter add/remove SDK dialog) just does not consult rvm. The same project opens fine with 3.0.1. The moment I use 3.1, everything is bad.
I also find attaching the Gems separately rather annoying when I have a Gemfile.
Anyone else in the same boat?
