The rails 4 answer:

add to gemfile.rb:

<pre><code>gem 'jquery-ui-rails'
</code></pre>

add to application.js:

<pre><code>//= require jquery
//= require jquery-ui
//= require jquery_ujs
</code></pre>

to add a specific module:

<pre><code>//= require jquery
//= require jquery-ui/yourmodulename
//= require jquery_ujs
</code></pre>

I'm not sure if restarting your server is explicitly required but it never hurts anything.

blocks|key|55249|text|有点低级错误，但如果这对任何人有帮助的话..|type|unstyled|depth|inlineStyleRanges|entityRanges|data|55250|我在我的资源中添加了jQuery-ui.js，然后添加了gem。然后从资源中删除了js，但我的IDE也从gem中删除了相同的文件。|55251|要解决此问题，请先删除gem，然后运行|55252|bundle+clean+--force|code-block|syntax|javascript|55253|然后|55254|bundle+install|55255|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|S|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|T|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|N|5|H|7|V|8|@]|9|@]|A|$I|J]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

Kind of a noob mistake, but if it helps anyone.. 

I added jQuery-ui.js in my assets and then added the gem. Then deleted the js from assets, but my IDE also deleted the same files from the gem.

To resolve, first remove the gem and then run,

<pre><code>bundle clean --force
</code></pre>

and then 

<pre><code>bundle install
</code></pre>

blocks|key|55310|text|我知道这是一个新手错误，但我发现这非常令人沮丧，总是忘记在我安装了新的东西后重新启动我的应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|55311|请确保在遵循上面的说明后重新启动rails服务器，它应该可以正常工作。|55312|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I know its a noob mistake but I found this very frustrating and always forget to restart my app after I have installed something new.

Make sure to restart your rails server after you have followed the instructions above and it should work perfectly.

blocks|key|271784|text|这可能只是一个重新启动WEBrick或您可能正在使用的任何其他服务器的问题，这样它就可以获得新的资产。对于WEBrick，只需转到服务器正在运行的终端窗口，然后使用CTRL-C终止进程，之后只需使用rails+s或其他命令重新启动服务器。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|271785|entityMap^0|2A|6|2R|7|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

It could just be a matter of restarting WEBrick or any other server you might be using so it picks up the new assets. For WEBrick just go to your terminal window where your server is running and <code>CTRL-C</code> to terminate the process, after that just restart it again using <code>rails s</code> or whatever the command to start your server is.

I am getting the following error even if I have jquery-ui in my application.js file

couldn't find file 'jquery-ui'
 (in /home/jeff/work/projects/a/media/app/assets/javascripts/application.js:14)

application.js

<pre><code>//= require jquery
//= require jquery_ujs
//= require jquery-ui
//= require jquery.validate.min
</code></pre>

Can anybody help me?

Couldn't find file 'jquery-ui'
