Error installing rubyMine, no SDK specified, but it is listed

Question

Getting \"Could not install gems:no SDK specified\" when trying to run any command such as starting the rails server. Why am I getting this and how can I get around it?

Answer 1

I tried following the advice in the above two answers and it still did not work for me. After making sure my project passed all rSpec I gave up on RubyMine and simply zapped the .idea sub-directory and got it to work after I recreated the RubyMine project from scratch.

Hope this helps.

p.s. my env is Mac Os X with RVM installed. Maybe something confused RubyMine with all that.
