I’m following the demo_app in Michael Hartl’s book Ruby on Rails 3 Tutorail. The demo is a simple Scaffold User name:string email:string
I’m getting an error in my application.html.erb file:
Errno::EINVAL in Users#index
Showing ~/demo_app/app/views/layouts/application.html.erb where line #6 raised:
Invalid argument - cscript //E:jscript //Nologo //U /tmp/execjs20120323-4388-1an85xw-0.js 2>&1
(in ~/demo_app/app/assets/javascripts/users.js.coffee)
3: <head>
4: <title>DemoApp</title>
5: <%= stylesheet_link_tag "application", :media => "all" %>
6: <%= javascript_include_tag "application" %>
7: <%= csrf_meta_tags %>
8: </head>
9: <body>
if I chnage line #6 to:
<%= javascript_include_tag "default" %>
The program will run perfectly except it won’t allow me to delete users (presumably because it’s not running the javascript).

try to uncomment gem ‘therubyracer’ and run bundle, and also it’s better to use last stable version of ruby
