我尝试过很多东西，但没有任何帮助。任何帮助都会很棒，提前谢谢。

您至少应该做两件事：停止加载重复文件（CDN与GEM结合使用）并重新组织您的application.js文件，以便 jQuery 后需要 Bootstrap

application.html.erb的<head>部分应该更贴近这一点：

<head>
  <title>ShiftInd</title>
  <link href='http://fonts.googleapis.com/css?family=Lato:300,400,700' rel='stylesheet' type='text/css'>
  <%= stylesheet_link_tag     'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>
</head>

除了jQuery-UI之外，你们已经有一个GEM加载这些文件，其中一些文件也有来自CDN的重复文件。您应使用application.scss将自己的样式表添加到@import。

<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css"></link>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css">
<link rel="stylesheet" href="/assets/style.css">
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script type="text/javascript" src="//code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript" src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>

您正在使用CDN拉入文件，同时还使用GEM实现相同的文件（jQuery / Font Awesome等）。

source 'https://rubygems.org'

gem 'rails', '4.2.3'
gem 'devise'
gem 'simple_form'
gem 'mailboxer'
gem 'chosen-rails'
gem 'acts_as_votable', '~> 0.10.0'
gem 'public_activity'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'coffee-script-source', '1.8.0'
gem 'paperclip', '~> 4.3.0'
gem 'bootstrap-sass', '~> 3.3.5.1'
gem "autoprefixer-rails"
gem 'font-awesome-sass', '~> 4.4.0'
gem 'jquery-rails'
gem 'jquery-ui-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc

group :production do
    gem 'pg'
    gem 'rails_12factor'
end

group :development, :test do
    gem 'sqlite3'
end

# gem 'therubyracer', platforms: :ruby

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use Unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

这是您的Gemfile的新版本，可用作参考：我更改了一些您不必做的事情，但可能会有所帮助：

切换Font-Awesome宝石
已添加Autoprefixer请参阅Bootstrap-sass宝石

Bootstrap需要使用Autoprefixer。 Autoprefixer增加了供应商使用Can I Use。中的值来为CSS规则添加前缀。

添加了Jquery-UI宝石（如果需要，也可以使用CDN，这只是另一种选择。原始文件可供参考，以下参考。）

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>

在你的application.js中，Bootstrap需要在jQuery之后。请参阅Docs。

//= require jquery
//= require jquery_ujs
//= require chosen-jquery
//= require bootstrap
//= require turbolinks
//= require_tree .

这是一个示例application.scss。

@import "bootstrap-sprockets";
@import "bootstrap";
@import "font-awesome-sprockets";
@import "font-awesome";
@import "jquery-ui";
@import 'style';

*您的style.css需要更改为style.scss

旧线程，我知道，但从我所看到的，答案是在推送到heroku之前手动预编译。经过大量的搜索，我做到了这一点，对我有用。

$ RAILS_ENV=production bundle exec rake assets:precompile

我把它放在git add之前的终端中。我也重新启动了heroku dyno。

bootstrap下拉列表无法在heroku上运行
