编辑 4、5 和 6
8 小时后,欢迎任何更多的想法 :) 也许这个错误已经知道并解决了,但是当你在 app/assets/的 .css.erb 文件中有这个时,我得到了我在编辑 2 和 3 中描述的行为样式表:
li {
background-image: url(<%= asset_path "logo_80px_80px.png" %>);
}
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。 After having some unrelated problems我发现了 precompiling the assets使用:
bundle exec rake assets:precompile RAILS_ENV=production
我的 application.css 文件,预编译生成:“application-79d6fafe46c10758d8f5a921f1e55ecd.css”,但尽管存在于 public/assets 文件夹中,但现在没有被提供。 application.js 文件运行良好(如 application-9a36deba94d6308ab9bebe4e30a93959.js)。我还注意到这个问题首先出现在我创建 .css.erb 文件之后,正如关于 precompilation 的文章所建议的那样.
对我尝试做的事情有什么想法吗?我将尝试撤消 .css.erb 文件,再次运行预编译,看看是否可以提供我的 application.css 文件。

问题不在于将 .css
文件更改为 .css.erb
。 erb 工作正常。使用 asset_path
函数时似乎会出现问题,例如:
.button_one {
background-image: url(<%= asset_path "activities/text_editor_toolbar.png" %>);
}
这可以提供正确的字符串,例如:assets/activities/text_editor_toolbar.png"
,它显示在已编译的 application-(hash).css
文件中在开发模式而不是生产模式下提供服务。这太奇怪了。:| :@
编辑 2好的,这变得更好了,但是更奇怪了。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,然后在生产中再次运行它 it'll spend ages and launch the 'Microsoft Console Based Script Host' just like it's precompiling the assets ,从输出看来它正在做,在最终呈现页面并成功提供应用程序(哈希).css 之前:

我遇到了完全相同的问题,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)解决了这个问题。

config.serve_static_assets = true
据我了解,如果您在 Apache 或 nginx 下运行,则将此选项设置为 false 是有意义的,但我的情况并非如此。
