application.css 未作为资产提供

Question

编辑 4、5 和 6

8 小时后，欢迎任何更多想法:) 也许这个错误已经被知道并解决了，但是当你有这个时，我得到了我在编辑 2 和 3 中描述的行为在 app/assets/stylesheets 的 .css.erb 文件中：

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 也用以下内容打破了它：

li {
    background-image: url(image-path("logo_80px_80px.png"));
}

ORIGINAL POST

我有一个 Rails 3.1 应用程序在生产模式下提供 application.css 文件。 遇到一些不相关的问题后，我发现了预编译资产使用：

bundle exec rake assets:precompile RAILS_ENV=production

我的application.css文件，预编译为生成：“application-79d6fafe46c10758d8f5a921f1e55ecd.css”，但尽管存在于public/assets文件夹中，但现在尚未提供服务。 application.js 文件运行良好（如 application-9a36deba94d6308ab9bebe4e30a93959.js）。我还注意到，这个问题在我创建 .css.erb 文件后首次出现，正如 预编译。

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 application.css 文件。

编辑 1

问题并非来自将 .css 文件更改为 .css.erb。而且 erb 工作正常。当使用 asset_path 函数时，问题似乎出现了，例如：

.button_one {
    background-image: url(<%= asset_path "activities/text_editor_toolbar.png" %>);
}

这可以给出正确的字符串，例如：assets/activities/text_editor_toolbar.png"，它显示在编译的文件中application-(hash).css 文件在开发模式下提供，但在生产模式下不提供，这太奇怪了：| :@

编辑 2 。 好吧，这变得更好了，但更奇怪了。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，它将花费很长时间并启动 ' Microsoft Console Based Script Host'就像它预编译资产一样，从输出来看，它似乎正在执行此操作，然后才最终渲染页面并成功提供应用程序-(hash).css

编辑3 您不需要首先在生产模式下运行它一次（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）。使用rake预编译资源后，只需在开发模式下运行，请求一个页面（这是必需的），然后在生产中运行并再次请求主页足以让它触发第二次预编译。

现在，我的机器（win 7-64位）完全重新启动后仍然存在。所以我认为这是一个持续存在的错误。

StackOverflow 是继续此讨论的最佳地点还是最好继续访问 Sprocket git-hub 页面，或者什么？

Answer 1

我遇到了完全相同的问题，并通过在 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

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。

Answer 2

前几天我遇到了这个问题，并通过编辑 Production.rb 文件解决了它，

config.assets.compress = true
config.assets.compile = true
config.assets.digest = true
config.assets.initialize_on_precompile = false

这是我最终得到的资产设置。我预编译我的资产，同时使用 capistrano 进行部署。

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，但服务器找不到这些文件。

Answer 3

为了简单起见，我喜欢使用 .css.scss 扩展名并使用：

li {
    background-image: image-url("logo_80px_80px.png");
}
