RubyTest in Sublime Text 2

Question

I am trying to get RubyTest to work in Sublime Text 2. I followed the Instruction on the Github Readme and get the following error. Does anyone know how I could fix this?

Answer 1

This worked for me:

If you're using RVM, open a project with command line from the project's folder:

subl .

Then, it'll hook the ruby version and gems.
