Sprockets::FileNotFound - couldn't find file 'jquery'
  (in /app/assets/javascripts/application.js:13):

这是我的application.js，

//= require jquery    <--- This is Line 13
//= require jquery_ujs
//= require jquery-ui
//= require jquery.turbolinks
//= require bootstrap
//= require social-share-button
//= require turbolinks
//= require_tree .

这是我的Gemfile：

source 'https://rubygems.org'

gem 'rails', '4.1.1'

group :assets do
  gem 'sass-rails', '~> 4.0.3'
  gem 'uglifier', '>= 1.3.0'

gem 'social-share-button', '~> 0.1.6'
gem 'ancestry', '~> 2.1.0'
gem "simple_form"

这是我的application.html.erb：

<!DOCTYPE html>
<html>
<head>
  <title>My Site</title>
  <!-- Style sheet -->
    <%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>

</head>
<body>

<%= render partial: "shared/nav" %>
  <% if notice %> <div class="alert alert-info"> <%= notice %> </div> <% end %>
  <% if alert %> <div class="alert alert-warning"> <%= alert %> </div> <% end %>
<%= yield %>

</body>
</html>

可能导致此错误的原因是什么？

Answer 1

Rails中的Gemfile中没有assets组。从该组中删除所有资产gems。

Answer 2

你正在使用铁路＆gt; 4，默认情况下包含jquery而不添加gem。

jquery-uj也是如此。等等。

另外，我注意到你正在使用jquery-turbolinks gem。

根据GitHub page，您应按以下顺序创建application.js：

//= require jquery
//= require jquery.turbolinks
//= require jquery_ujs
//
// ... your other scripts here ...
//
//= require turbolinks

您的订单不同......

Answer 3

在套件中的Javascripts文件夹中，页面底部将如下所示......

'//=require jquery'
'//=require jquery_ujs'
'//=require turbolinks'
'//=require_tree .'

在我的情况下，我的网站中没有任何jquery所以我采用了＆＃34; =＆＃34;出来，这解决了我的问题！看起来很漂亮我可能会加上！

'// require jquery'
'// require jquery_ujs'
'// require turbolinks'
'// require_tree .'

谢谢Chris Dunphy

找不到'jquery'文件
