ExecJS::RuntimeError in Demo#index

Mon Jun 11 08:05:09 UTC 2012

Hi All,

I installed Ruby on Rails from ports and www/node and started learning. 
After executing 'rails generate controller demo index' I got the error 
below when trying to access my_ip:3000/demo/index.

What can I do to fix it?

  ExecJS::RuntimeError in Demo#index

Showing 
//usr/home/zodias/rails_learn/simple_cms/app/views/layouts/application.html.erb/ 
where line *#6* raised:

|["ok","(function() {\n\n\n\n}).call(this);\n"]
   (in /usr/home/zodias/rails_learn/simple_cms/app/assets/javascripts/demo.js.coffee)|
