So here is the error after starting the server and going to the site. http://i.imgur.com/4plRQOS.png . I'm doing this tutorial: http://guides.rubyonrails.org/getting_started.html (step 4.3). I've tried all the solutions on the net (changing runtimes.rb/adding node.js to the path/ installing therubyracer but for some reason would not install). Really need help on this. No idea how to fix. Thanks.
