gem 'exec.js' gem 'therubyracer.js'All that happens is you get a different error
Could not find gem 'therubyracer.js (>= 0) ruby' in the gems available on this machine.Further digging revealed that this can be fixed by installing node.js unfortunately there doesn't solve it either. Then I gave up on my current AMI and thought to start all over and to follow the instructions given here and here.
/usr/local/rvm/rubies/ruby-1.9.3-p125/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>': It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. Latest version currently installed. Aborting.But the persistent errors just wouldn't go away, then my luck changed and I found an AMI that has all this installed. Unfortunatley I forgot to make a note of the machine ID but I created a new AMI from it for my own use so I am safe!
