虽然，类似的问题，但提出的解决方案都没有奏效。
在从Rails 4.0.0升级到Rails 4.1.4之前，一切正常。作为调试的一部分，我删除了Gemfile.lock并使用“bundle install”重新生成
Rails 4.1.4 Ruby 2.0
由于2.12.x中的问题无法使用Rails 4.1.4，链轮限制在2.11.0。 sass-rails限制在4.0.2。作为限制链轮版本的同一问题的一部分。
的Gemfile：
source 'https://rubygems.org'
gem 'rails', '= 4.1.4'
gem 'sass-rails', '4.0.2'
gem 'haml-rails'
gem 'coffee-rails'
gem 'jquery-rails'
gem 'jquery-ui-rails'
gem 'uglifier'
gem 'therubyracer'
gem 'turbolinks'
group :development do
gem 'thin'
gem 'erb2haml'
gem 'capistrano'
gem 'rvm-capistrano'
gem 'rspec-rails'
end
gem 'jbuilder'
gem 'mysql2', '~> 0.3.12b5'
gem "sprockets", "2.11.0"
gem 'better_errors', group: :development
gem 'sprockets_better_errors', group: :development
gem 'binding_of_caller', group: :development
gem 'quiet_assets', group: [:development, :test]
# Lots more gems omitted...
摘自Gemfile.lock：
jquery-rails (3.1.1)
railties (>= 3.0, < 5.0)
thor (>= 0.14, < 2.0)
jquery-ui-rails (5.0.0)
railties (>= 3.2.16)
包含jquery.ui.all行的CoffeeScript：

在深入研究之后，结果表明在项目中包含jquery-ui-rails的语法已经改变了javascript和样式表！ Rails 4.1.x的工作解决方案是：
在你的Gemfile中，只需包含gem：
gem 'jquery-ui-rails'
您无需指定源或分支。
而不是旧的方式（对于一切）：
#= require jquery.ui.all
您现在应该使用：
#= require jquery-ui
注意＆＃34;。＆＃34;成为＆＃34; - ＆＃34;
如果您想要包含特定组件，那么它也会发生变化。而不是：
#= require jquery.ui.sortable
现在：
#= require jquery-ui/sortable

我遇到了一个非常类似的问题，这里的解决方案对我有用：Heroku Rails 4-- FileNotFound jquery.ui.all
在宝石文件中，更改行
gem 'jquery-ui-rails'
到
gem 'jquery-ui-rails', github: 'joliss/jquery-ui-rails', branch: 'rails-4.0.2'
然后运行
bundle update

除了@Michael Lang的回答，我还要做另外一件事让它发挥作用：
//= require jquery-ui必须遵循//= require jquery_ujs
所以它看起来像这样：
//= require jquery
//= require jquery_ujs
//= require jquery-ui
//= require_tree .
