Get RubyMine to find existing Gems

Hello

I am very new to Ruby and I am evaluating Ruby Mine

I have one annoying issue, when I run tests using guard in a terminal session everything is fine, once I have done bundle

So as far as I am concerned, all of my required GEMS are installed and ready to go

So howcome I get messages from Ruby Mine saying Gem not found?

The IDE never seems to install the missing gems in bulk

I can only install them one by one

I am using Ruby 2.3.1 but notice the path below

.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0

Is that ok?

My environment info is below

How do I tell Ruby Mine to use the same folder for my gems as terminal is using?
