Rubymine pg install error - ruby-on-rails

Question

Ive been trying out Rubymine for a small rails project and would really like the debugging to work.
The project is a rails API and uses Postgres running on my Mac with El Capitan.
The problem i have is Rubymine is complaining of 'No Rails found in SDK'
I thought the solution to this was to run bundle install from the Rubymine menu.
However that consistently fails at installing pg:
....

An error occurred while installing pg (0.18.4), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.4'` succeeds before bundling.
I have tried numerous of the other solutions on stack overflow including:
Bundler::GemNotFound: Could not find rake-10.3.2 in any of the sources
An error occurred while installing pg (0.17.1), and Bundler cannot continue
and have installed postgres on my machine (i think) using the app and brew.
Any ideas for making this work would be greatly appreciated!

I don't think the error is RubyMine-related; I think it's system-related.
That is, if you do gem install pg on the command line, I suspect you'll get the same error.
I use rvm and it just works. It installs the necessary system libraries. (That said, others have had difficulties from time to time.)
If you're interested in using rvm, google "install rvm" to get the link for the installation instructions.
That said, you should make sure RubyMine is configured for your project to use the same Ruby you are using on the command line. That way, you will get consistent results in both environments.
Also. just FYI, you can email support#jetbrains.com for RubyMine questions.
