Sprockets File not Found Exception

Question

I was trying out some sample applications for Rails. I created some controllers and pages. But when i try to access one of them i get an exception on the webpage:

Sprockets::FileNotFound in Pages#home
Showing c:/railscode/test_app/app/views/layouts/application.html.erb
where line #6 raised:

couldn't find file 'jquery'
  (in c:/railscode/test_app/app/assets/javascripts/application.js:7)
Extracted source (around line #6):

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

Rails.root:`c:/railscode/test_app`

I created some controllers using the command:

$ rails generate controller Pages home contact

  create  app/controllers/pages_controller.rb
   route  get "pages/contact"
   route  get "pages/home"
  invoke  erb
  create    app/views/pages
  create    app/views/pages/home.html.erb
  create    app/views/pages/contact.html.erb
  invoke  rspec
  create    spec/controllers/pages_controller_spec.rb
  create    spec/views/pages
  create    spec/views/pages/home.html.erb_spec.rb
  create    spec/views/pages/contact.html.erb_spec.rb
  invoke  helper
  create    app/helpers/pages_helper.rb
  invoke  rspec
  create     spec/helpers/pages_helper_spec.rb
  invoke  assets
  invoke    js
  create      app/assets/javascripts/pages.js
  invoke    css
  create      app/assets/stylesheets/pages.css

Just wanted to know where the problem could be and where to look? I am accessing the page by the URL: http://localhost:3000/pages/home

Un-commenting the line

//= require jquery

in application.js file and restarting the application is what worked for me.

Had a similar problem with FileNotFound for twitter/bootstrap after installing http://metaskills.net/2011/09/26/less-is-more-using-twitter-bootstrap-in-the-rails-3-1-asset-pipeline/

I did rake assets:clean assets:precompile, but that didn't help. What helped was restarting the rails application as suggested by afaf12.

For me, the solution was to run yarn install. YMMV

In rails 6.x.x the problem can be solved by executing

bundle exec rails webpacker:install

Just add a comment to your config/initialize/assets and then restart your rails server.

Rails.application.config.assets.paths << Rails.root.join('node_modules')

It's quite possible that your jquery-rails gem is outdated. When I ran into a similar error, updating the gem solved the issue.

Did you create this as a Rails 3.1 application from scratch? Or are you downloading code from somewhere (or updating an older app)?
