Sprockets::FileNotFound couldn't find file 'jquery-fileupload/basic'

I am attempting to upload multiple pictures with jquery file upload. In my application.js file I added //= require jquery-fileupload/basic and in my Gemfile I added jquery-fileupload-rails under the assets group. This causes the error: couldn't find file jquery-fileupload/basic. I have reset my rails server and checked for spaces in application.js however the error stays. Any help would be greatly appreciated

application.js

//= require jquery
//= require jquery_ujs
//= require jquery-fileupload/basic
//= require jquery.ui.datepicker
//= require jquery.ui.tooltip
//= require jquery-ui-1.10.4.custom.min
//= require jquery.timepicker.min
//= require bootstrap/dropdown
//= require bootstrap/modal
//= require raty
//= require_tree .

gemfile

gem 'sass-rails', '~> 4.0.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'

group :assets do
    gem 'jquery-ui-rails', '~> 4.2.1'
  gem 'jquery-fileupload-rails'
end

put it outside the assets group and run bundle install.

btw jquery-ui-rails does not belong there either
