jQuery UI rails gem error

So I'm using ruby on rails and the jquery datatable and just added the jquery-ui-rails gem as per Rails Cast #340 Did the bundle install. This is my application.js:

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require jquery.ui.all
//= require_tree .
//= require dataTables/jquery.dataTables
//= require dataTables/jquery.dataTables.bootstrap

and here's my application.css file:

/*
 *= require jquery.ui.all
 *= require_tree .
 *= require_self
 *= require dataTables/jquery.dataTables
 *= require dataTables/jquery.dataTables.bootstrap
 */

I restarted my server, and again and again but this error persists:

couldn't find file 'jquery.ui.all'
in ...app/assets/stylesheets/application.css:13)
