I'd like to set up each Ruby project/app with the associated Ruby version, rspec version and gems.
For the most part, I'll be using using the current version of Ruby, but for several apps I have to use Ruby -1.9.3 and the appropriate rspec version.
Gemfile
source "https://rubygems.org"
ruby '1.9.3'
gem 'rspec', "1.9.3"
gem 'json'
gem 'spreadsheet'
gem "pdf-reader", "~> 1.3"
Running;
bundle install
Results in;
$ bundle install

Could not find gem 'rspec (= 1.9.3) ruby' in the gems available on this machine
Not sure what to do from here.
