Rails 4 - how to install "jquery-ui"?

Question

For using jquery autocomplete plugin, I need to install jquery-ui gem.

So far, I had in my gemfile following:

gem 'jquery-rails'

So I added:

gem 'jquery-ui-rails'

And to application.js I added:

//= require jquery
//= require jquery_ujs
//= require jquery-ui

and to application.css:

 *= require_self
 *= require jquery.ui

bundle update, restart server and:

couldn't find file 'jquery.ui'

I am using in the app also turbolinks. Do I miss a gem something or something in order to make jquery-ui work in the app?

Thanks.

EDIT:

All jquery-related stuff in tehe Gemfile:

gem 'jquery-rails'
gem 'jquery-ui-rails'
gem 'jquery-turbolinks'

To update this answer, the current convention is:

//= require jquery-ui

and for css:

/*
*= require jquery-ui
*/

for specific modules:

//= require jquery-ui/draggable
