Can't find 'jquery-ui' Rails 3.2

问题

I have been looking everywhere to figure out this problem. I already downgraded the jquery-rails gem to 2.3.0 in my gemfile. But when I include jquery-ui in application.js I still get the Sprokets::FileNotFound error.

couldn't find file 'jquery-ui'
  (in /home/richard/projects/pickaxe/mini-projects/depot-app/app/assets/javascripts/application.js:14)

This is my application.js file:

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
// WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD
// GO AFTER THE REQUIRES BELOW.
//
//= require jquery
//= require jquery-ui
//= require jquery_ujs
//= require_tree .

I am dying to find out why this isn't working...

If you are using the jquery-ui-rails gem, you need to use require jquery.ui.all instead of require jquery-ui. If you don't want to use the gem, make sure that you have a jquery-ui.js file in your app/assets/javascripts folder.

UPDATE

As of version 5.0.0, use require jquery.ui.

I tried downgrade jquery-rails on my application, That works fine.

Put gem 'jquery-rails', "~> 2.3.0" to Gemfile
Remove Gemfile.lock -> rm Gemfile.lock
Run bundle install
Put //= require jquery-ui to application.js

Started GET "/assets/application.js?body=1" for 127.0.0.1 at 2013-06-08 13:16:50

Could you post your Gemfile ?
