我是 Heroku 的新手。当我在本地运行这个 rails 应用程序时，它工作正常，当我部署到 heroku 时，它会中断。请看图片。我在该图像内指向箭头。

在这里本地工作正常，它假设以这种方式工作。 在此处输入图像描述

CSS 在这里破坏了图像，并且不应该是这样的。只发生在 Heroku 服务器中。 在此处输入图像描述

我在 rails 应用程序中有多个 CSS 文件，其中大约 9 个。
我正在使用带有 Ruby 1.9.3 的 Rails 3.2

我一直在尝试解决这个问题并到处寻找这个解决方案，但没有运气。之前还好好的，不知道怎么回事？

任何帮助表示赞赏，如果解决了，我会将答案标记为正确。

谢谢！

更新：当我做 git push heroku 时，这就是我所看到的：

       Asset precompilation completed (105.95s)

在 application.css 中，我看到了

/*
*= require_self
*= require_tree .
*/

/* rest of file omitted */

这可能与资产管道有关。

确保 application.css 需要您的所有资产或添加到

config.assets.precompile += ['admin.js', 'admin.css', 'swfObject.js']

在 application.rb 中。

资产在本地运行时编译，但不在生产环境中编译。

编辑：为了让 active_admin 发挥出色，不要将其包含在 application.css 中，即：删除

require_tree .

并分别要求每个文件/目录。
