Set up the Ruby environment with RVM or rbenv in Mac

edit

Hello, I'm new to Ruby and OpenStudio measure development. I have a question upon how to set up the environment of OpenStudio library for Ruby in Mac.

Currently I'm running Ruby through rvm(Ruby Version Manager) which is a stand alone ruby directory so that I won't mess up with the System Ruby. Here's what I did: First I ran gem install openstudio to get the library installed. After that I ran require "openstudio" in the IRB, the error message prints:

LoadError: cannot load such file -- openstudioutilitiescore

My ruby version in the rvm is 2.0.0p643 and OpenStudio v. 1.7.5.

Any help would be appreciated!

Thanks David.

Here is what I did after:

I created the openstudio.rb file with the content:

require '/Applications/OpenStudio 1.7.5/Ruby/openstudio.rb'

And then saved it to:

/Users/my_user_name/.rvm/rubies/ruby-2.0.0-p643/lib/ruby/site_ruby/

Then I uninstalled the openstudio package (which I install with gem earlier)

I tried to run require "openstudio" again in the irb.

The reports prints:
