couldn't find file 'jquery' with type 'application/javascript'

This might seem a repeated question but none of the solutions seem to work for me. I have gem jquery-rails in my Gemfile. Also, the lines

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .

And this is my Gemfile:

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.1'

# Use SCSS for stylesheets
#gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
#gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/rails/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
#gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use Unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug'
  # Use mysql as the database for Active Record
  gem 'mysql2'
  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console', '~> 2.0'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

My application.html.erb :

<!DOCTYPE html>
<html>
<head>
  <title></title>
  <%= stylesheet_link_tag 'application', media: 'all' %>
  <%= javascript_include_tag 'application' %>
  <%= csrf_meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

I cannot start my Rails application. I do not understand what is the issue. My ruby version is 2.1.6 Please help.

This occurs often times because the Gemfile lacks the gems needed for the jquery dependencies to resolve themselves.

In Rails 5.x, add this to the Gemfile:

gem 'jquery-rails', '~> 4.3', '>= 4.3.3'
gem 'rails-ujs', '~> 0.1.0'

After this, run bundle Install.

Restart the server for it to update the latest changes and voila, it works!

This issue can be fixed by the following steps bellow.

  1. Make sure that the require jquery statement is there in application.js

    //= require jquery

    //= require jquery_ujs

  2. Make sure that all the required gems are present in the Gemfile, if it is not present add it and execute bundle install command.

    gem 'jquery-rails', '~> 4.3', '>= 4.3.3'

    gem 'rails-ujs', '~> 0.1.0'3.'

  3. If it is still showing the error update your node by runnig

    sudo npm update npm -g

Finally refresh your application.

You simply need to add gem 'jquery-rails' in Gemfile and run bundle install. It worked for me.

Go to gemfile and make sure that gem jquery-rails is uncommented. Run bundle install. That should do it.

In your controller file you can not tell rails not to use a layout by writing

layout false

Directly under your controller class on the second line

class ExampleController < ApplicationController
layout false

This is caused because of default javascript runtimes that are already available in Windows but has some compatibility issues. The most easy workaround is to install nodejs from http://nodejs.org/download/ and then restart your PC. This solves all the issues.

For more details about the issue, please refer to this page : ExecJS::RuntimeError on Windows trying to follow rubytutorial
