Basic Hello, Rails! not working

so I am very new to ruby and rails and I'm following this tutorial exactly: http://guides.rubyonrails.org/getting_started.html

I am having trouble with the basic "Hello, Rails!" output on the localhost:3000 as even when I follow along and make the appropriate changes to 

app/views/welcome/index.html.erb

and

config/routes.rb

localhost:3000 still displays the default Ruby on Rails Welcome screen instead of "Hello, Rails!"

in the file

app/views/welcome/index.html.erb

I have the following code:

<h1>Hello, Rails!</h1>

in the file

config/routes.rb

I have the following code:

Blog::Application.routes.draw do
  get "welcome/index"

  # You can have the root of your site routed with "root"
  # just remember to delete public/index.html.
   root :to => 'welcome#index'


end

and I initially generated the controller with

rails generate controller welcome index

Thank you!

EDIT:

I removed the public/index folder and now get the following error in the browser:

ExecJS::RuntimeError in Welcome#index

Showing C:/blog/app/views/layouts/application.html.erb where line #6 raised:


  (in C:/blog/app/assets/javascripts/welcome.js.coffee)

Extracted source (around line #6):

3: <head>
4:   <title>Blog</title>
5:   <%= stylesheet_link_tag    "application", :media => "all" %>
6:   <%= javascript_include_tag "application" %>
7:   <%= csrf_meta_tags %>
8: </head>
9: <body>

Rails.root: C:/blog
Application Trace | Framework Trace | Full Trace

app/views/layouts/application.html.erb:6:in `_app_views_layouts_application_html_erb__607271608_36500496'

EDIT 2:

rake routes gives:

welcome_index GET /welcome/index(.:format) welcome#index
        root           /                   welcome#

EDIT 3:

source of welcome.js.coffee:

# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://jashkenas.github.com/coffee-script/

source of Gemfile:

source 'https://rubygems.org'

If you are not planning to use turbolinks you can avoid installation of turbolinks with rails by running new your_project_name --skip-turbolinks when creating your rails project. This way you will avoid this kind of bugs while you are learning the basics.

yes,truly worked for me. deleted following line from C:/blog/app/views/layouts/application.html.erb:

<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>

Solved it:

go to

C:/blog/app/views/layouts/application.html.erb line #6

and remove the javascript line.

But this is really stupid and I think the real solution is to switch to linux.

Check if your controller file is welcome_controller.rb. Also Check if the class name is "WelcomeController".

EDIT:

It seems that you are getting a ExecJS exception. Please add a javascript runtime to the gemfile:

gem  'therubyracer'

I hate windows.
