i'm working on Michael Hartl's ruby on rails tutorial and i've run into a problem that i haven't been able to fix for days.
when trying to load the page, chrome reads:
Sprockets::FileNotFound in StaticPages#home
Showing /Users/azimmer/rails_projects/sample_app/app/views/layouts/application.html.erb where line #7 raised:
couldn't find file 'jquery'
(in /Users/azimmer/rails_projects/sample_app/app/assets/javascripts/application.js:13)

<title><%= full_title(yield(:title)) %></title>
<%= stylesheet_link_tag "application", media: "all",
"data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>
<%= render 'layouts/shim' %>
</head>
Rails.root: /Users/azimmer/rails_projects/sample_app
here is my gemfile:
source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0
gem 'rails', '4.0.2'
gem 'bootstrap-sass', '2.3.2.0'
gem 'bcrypt-ruby', '3.1.2'
group :development, :test do
gem 'sqlite3', '1.3.8'
gem 'rspec-rails', '2.13.1'
end
group :test do
gem 'selenium-webdriver', '2.35.1'
gem 'capybara', '2.1.0'
gem 'sass-rails', '4.0.2'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '2.3.0'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'
gem 'factory_girl_rails', '4.2.1'
end
group :doc do
gem 'sdoc', '0.3.20', require: false
end
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
and here is my application.html.erb file:
<!DOCTYPE html>
<html>
<head>
<title><%= full_title(yield(:title)) %></title>
<%= stylesheet_link_tag "application", media: "all",
"data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>
<%= render 'layouts/shim' %>
</head>
<body>
<%= render 'layouts/header' %>
<div class="container">
<%= yield %>
<%= render 'layouts/footer' %>
<%= debug(params) if Rails.env.development? %>
</div>
</body>
</html>
my application.js file is totally untouched. i have tried everything from adding gem rubyracer, to editing the runtimes.rb file in execjs recommended on another thread. i'm considering just starting over from scratch in order to get everything to work, at least in that case i would relearn a lot of what i've learned, but i'm hoping someone can at least help me figure out what is going on here.
thanks a bunch for your help!
cheers,
alex
EDIT
it works if i change the line from
<%= javascript_include_tag 'application', "data-turbolinks-track" => true %>
to
<%= javascript_include_tag :default, "data-turbolinks-track" => true %>
could anyone explain what this means? and how making that change might affect my application in a negative way? thank you for the help!
