资产管道不提供资产，但没有错误。这个配置看起来是否正确？

Question

我是一个RoR新手（但是经验丰富的开发人员），我一直很享受......但是我已经用Asset Pipeline打了一堵砖墙！我有一个遗留应用程序，我正在修改以使用资产管道。我已经在SO和其他网站上阅读过文章，但我无法让这个工作。以下是详细信息：

Ruby版本：2.0.0-p353

Rails版本：3.1.12

目录 app / assets / javascripts 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

目录 app / assets / stylesheets 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

文件 application.css 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localhost:3000/assets/application.js时，我只是获取了返回的application.js文件的内容。同样适用于application.css。然而，application.js中有一个显着的尾随分号：

//= 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
;

我试过追逐那个拖尾的分号而没有运气。我已经改变了require语句的顺序，认为我可能能够缩小.js代码中的任何语法错误，但这种努力是不成功的。

当我的页面被渲染时，它没有任何样式或js（正如预期的那样，因为资产管道不起作用）。

我也尝试在application.css和application.js中使用require_tree .指令，而不是明确列出每个文件，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。似乎Rails认为资产得到了正确的服务：

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，我的配置有任何明显的遗漏吗？任何人都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RailsGuides＃318“升级到Rails 3.2”）。现在我的js和css正在传送到浏览器：

服务器控制台显示单独交付的资产（开发模式）：
