ruby-on-rails - Asset Pipeline 不提供 Assets ，但没有错误。这个配置看起来正确吗？

Question

我是 RoR 新手(但经验丰富的开发人员)，我一直很喜欢它……但我在 Assets 管道方面遇到了障碍!我有一个遗留应用程序，我正在对其进行修改以使用 Assets 管道。我在 SO 和其他网站上阅读了一篇又一篇文章，但我就是无法正常工作。以下是详细信息:

ruby 版本:2.0.0-p353

Rails 版本:3.1.12

app/assets/javascripts 目录的内容:

application.js          
bootstrap.js            
event_calendar.js       
jquery-ui-timepicker-addon.js   
jquery-ui.js            
jquery.js
jquery.prettyPhoto.js
jrails.js
mce_editor.js
rails.js
/tiny_mce

文件application.js的内容:

//= require bootstrap
//= require event_calendar
//= require jquery
//= require jquery.prettyPhoto
//= require jquery-ui
//= require jquery-ui-timepicker-addon
//= require jrails
//= require mce_editor
//= require rails
//= require_tree ./tiny_mce

app/assets/stylesheets 目录的内容:

application.css         
/blueprint          
bootstrap-responsive.css    
bootstrap.css           
common.css          
contributed.css         
event_calendar.css      
jquery-custom.css
jquery-ui-timepicker-addon.css
marketing.css
prettyPhoto.css
registration.css
sysadministration.css
template.css
/ui-darkness

application.css 文件的内容:

/*
*= require bootstrap
*= require bootstrap-responsive
*= require common
*= require contributed
*= require event_calendar
*= require jquery-custom
*= require jquery-ui-timepicker-addon
*= require marketing
*= require prettyPhoto
*= require registration
*= require sysadministration
*= require template
*= require_tree ./blueprint
*= require_tree ./ui-darkness
*/

在config/application.rb中设置:

config.assets.enabled = true

app/views/layouts/application.html.erb 中的助手

<%= stylesheet_link_tag    "application" %>
<%= javascript_include_tag "application" %>

config/environments/development.rb 中的设置:

config.assets.compress = false
config.assets.compile = true
config.assets.debug = true  

文件夹/public/assets的内容:

(empty)

当我浏览到 localhost:3000/assets/application.js 时，我只是得到返回的 application.js 文件的内容。同样适用于 application.css。但是，application.js 中有一个明显的尾随分号:

//= require bootstrap
//= require event_calendar
//= require jquery
//= require jquery.prettyPhoto
//= require jquery-ui
//= require jquery-ui-timepicker-addon
//= require jrails
//= require mce_editor
//= require rails
//= require_tree ./tiny_mce
;

我曾尝试追查尾随的分号，但没有成功。我已经更改了 require 语句的顺序，认为我可以减少 .js 代码中的任何语法错误，但这项努力没有成功。

呈现我的页面时，它没有任何样式或 js(正如预期的那样，因为 Assets 管道不工作)。

我也曾尝试在 application.css 和 application.js 中使用 require_tree . 指令，而不是显式列出每个文件，但这也不起作用。

最后，我的服务器控制台中没有出现任何错误。看起来 Rails 认为 Assets 被正确提供:

Started GET "/assets/application.css?body=1" for 127.0.0.1 at 2014-08-02 15:31:02 -0400
Served asset /application.css - 304 Not Modified (0ms)

Started GET "/assets/application.js?body=1" for 127.0.0.1 at 2014-08-02 15:31:02 -0400
Served asset /application.js - 304 Not Modified (0ms) 

根据我提供的信息，我的配置是否有明显的遗漏？任何人有一些建议让这个工作？？

谢谢!

我决定升级到 Rails 3.2.18，这解决了这个问题(我遵循了 RailsGuides #318“升级到 Rails 3.2”)。现在我的 js 和 css 被传送到浏览器:

并且服务器控制台显示正在单独交付的 Assets (开发模式):
