application.css不作为资产
编辑4,5和6
8个小时，欢迎任何更多的想法:)也许这个bug已经知道并解决了，但是我得到了我在编辑2和3中描述的行为，当你在app / assets / stylesheets中的.css.erb文件中有这个时：
li { background-image: url(); } 问题部分似乎是asset_path方法调用，但.css.scss也打破了它：
li { background-image: url(image-path("logo_80px_80px.png")); }

我有一个Rails 3.1应用程序，它在生产模式下提供application.css文件。 在遇到一些不相关的问题后，我发现了使用以下方法预编译资产 ：
bundle exec rake assets:precompile RAILS_ENV=production
我的application.css文件，预编译生成：’application-79d6fafe46c10758d8f5a921f1e55ecd.css’但现在尽管存在于public / assets文件夹中但仍未提供服务。 application.js文件正常运行（如application-9a36deba94d6308ab9bebe4e30a93959.js）。 另外我注意到这个问题首先出现在我创建.css.erb文件后，正如预编译文章所建议的那样。
对我尝试做什么的任何想法？ 我将尝试撤消.css.erb文件，再次运行预编译，看看我是否提供了我的application.css文件。
编辑1
问题不是来自将.css文件更改为.css.erb 。 并且erb工作得很好。 使用asset_path函数时似乎出现问题，例如：
.button_one { background-image: url(); }
这可以提供正确的字符串，例如： assets/activities/text_editor_toolbar.png" ，它显示在编译的application-(hash).css文件中，该文件在开发中提供但不是生产模式。这太奇怪了。：|： @
编辑2好的，这只是变得更好，但更奇怪。 似乎如果我在生产模式下运行一次，它就会失败。 在开发中再次运行它，然后再次在生产中运行它将花费很长时间并启动“基于Microsoft控制台的脚本主机”，就像它在最终呈现页面和服务之前预编译资产一样 ，从输出看起来像它正在做的那样application-（hash）.css成功：

编辑3您不需要先在生产模式下运行一次（即它实际上是在开发中运行的行为，它会触发生产模式以（？）重新预编译资产）。 在使用rake预编译资产之后，它只需要在开发模式下运行，请求页面（这是必要的），然后在生产中运行并再次请求主页足以触发看起来像第二个预编译的内容。
这已经幸免于我的机器完全重启（赢7-64bit）。 所以我认为这是一个一致的错误。
StackOverflow是继续讨论的最佳位置，还是最好继续使用Sprocket git-hub页面 ？
我有完全相同的问题，并通过在我的production.rb文件中将此选项更改为true（默认情况下为false）来解决它。
# Disable Rails's static asset server (Apache or nginx will already do this) config.serve_static_assets = true
根据我的理解，如果你在Apache或nginx下运行，将此选项设置为false是有意义的，这不是我的情况。
前几天我遇到了这个问题，并通过编辑production.rb文件解决了这个问题
config.assets.compress = true config.assets.compile = true config.assets.digest = true config.assets.initialize_on_precompile = false
我最终得到的资产设置。 我在使用capistrano进行部署时预编译了我的资产。
在编辑资产设置之前，我遇到了完全相同的问题。 正在请求.css并将其编译到我的public / assets文件夹中，但服务器无法找到这些文件。
为了简单起见，我喜欢使用.css.scss exstension并使用：
li { background-image: image-url("logo_80px_80px.png"); }
