Ruby on rails 3.1 Rails 3.1未解析的资产

问题

我有一个Rails 3.0.4应用程序，我按照来自的说明升级到3.1.4

现在我遇到了资产的问题，因为它们没有得到解决，在服务器日志中给出如下消息：

Started GET "/assets/application.css" for 127.0.0.1 at 2012-04-08 03:57:13 -0500
Served asset /application.css - 404 Not Found (15ms)

ActionController::RoutingError (No route matches [GET] "/assets/application.js"):

这些文件位于

assets

目录中：

$ ls app/assets/*/application*
app/assets/javascripts/application.js   app/assets/stylesheets/application.css

其中包括：

$ cat app/assets/javascripts/application.js
//= require jquery
//= require jquery_ujs
//= require_self
//= require_tree .
$ cat app/assets/stylesheets/application.css
/*
*= require_self
*= require_tree .
*/

我想一切都配置好了。在这里，我放置了一些文件块：

• Gemfile

  ，包含所需的资产gems：

  group :assets do
    gem 'sass-rails', '~> 3.1.3'
    gem 'coffee-rails', '~> 3.1.0'
    gem 'uglifier'
  end
  

• application.rb

  ，已启用资产：

  config.assets.enabled = true
  config.assets.version = '1.0'
  

• development.rb

  ：

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

• 最后<代码>应用程序.html.erb布局：

  <%= stylesheet_link_tag 'application' %>
  <%= javascript_include_tag 'application' %>
  

• 然后我执行

  rake资产：预编译
  ：
  
  $ bundle exec rake assets:precompile
  /usr/local/rvm/rubies/ruby-1.9.2-p318/bin/ruby /usr/local/rvm/gems/ruby-1.9.2-p318/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets
  /usr/local/rvm/rubies/ruby-1.9.2-p318/bin/ruby /usr/local/rvm/gems/ruby-1.9.2-p318/bin/rake assets:precompile:nondigest RAILS_ENV=production RAILS_GROUPS=assets
  
  然后，执行服务器（
  rails s
  ）并再次请求图像（
  rails.png
  ）：

所以怎么了？，我做错什么了吗？
据我所知，所有预编译的资产都被移动到资产文件夹中
这意味着javascript、样式表和图像的内容将组合在

localhost:3000/assets

中
所以如果你搜索

localhost:3000/assets/images/rails.png

它应该位于

app/assets/images/images/rails.png

。 因此，404

为了保持目录整洁，我建议将所有图像保存在app/assets/images/中，并使用

asset\u path（'rails.png'）

将它们指向生产模式吗？您是否运行过bundle exec rake assets:precompile？另外，您是否包含链轮库？@pjumble还没有，即使我处于开发环境下，这是否必要？我假设您处于生产模式，但不，在开发模式下，您不必预编译资产。如果从URL中删除

/images/

，图像是否有效？（

http://localhost:3000/assets/rails.png

）@pjumble它能工作<代码>http://localhost:3000/assets/rails.png谢谢
