creating new application using ruby on rails for EmberJs and when running "rails s" on ubuntu 14.04 getting following error

Extracted source (around line #6): 



    <%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
    <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
    <%= csrf_meta_tags %>

To resolve above error, tried following cases.
1) As already posted question reading above error
ExecJS::RuntimeError in Users#index (RoR)
a) changed ~/.rvm/gems/[email protected]/gems/execjs-1.4.0/lib/execjs/runtimes.rb
b) changed ~/.rvm/gems/[email protected]/gems/execjs-2.2.2/lib/execjs/runtimes.rb

JScript = ExternalRuntime.new(
    :name        => "JScript",
    :command     => "cscript //E:jscript //Nologo",
    :runner_path => ExecJS.root + "/support/jscript_runner.js",
    :encoding    => 'UTF-8' # CScript with //U returns UTF-16LE
)

but still getting same error.

2) If commented out //= require vendor in /app/assets/javascripts/application.js. Then above error will disappear. Then getting following errors
TypeError: Ember.ApplicationController is undefined
TypeError: Ember.ApplicationView is undefined

3) if changing 

<%= javascript_include_tag 'default', 'data-turbolinks-track' => true %>
Then getting error NetworkError: 404 Not Found localhost:3000/javascripts/default.js

Setup Details:
1) ruby --version ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-linux]
2) rails --version Rails 4.1.7
3) gem --version 2.4.4
4) nodejs --version v0.10.33

Nothing seems to be work, Can anyone through light to resolve issue?

Thanks to all in advance.

The things you are doing tell me that you are completely lost on what is going on, I highly recommend that you follow a rails tutorial. – givanse

Working fine with following changes.
1) placed the files[ember.js,handlerbars.js and jquery.js] in /vendor/assets/javascripts.
Note these files were downloaded from http://emberjs.com/ under StartKit.
2) included line //= require_tree ../../../vendor/. under app/assets/javascripts/application.js

If you are placing ember js into your vender/assets you're doing it wrong. Most JavaScript libraries are compiled into gems for easier use in Rails and ember is no exception. Try this tutorial instead and use ember-rails or your project will likely have issues down the line.

Oh also, make sure to remove the calls to turbolinks cuz that does not place nice with ember
