【问题描述】：

我编译我的资产没有错误，它们在开发环境中工作没有问题，但它们都在生产中中断。我检查了我的日志文件，它似乎没有引用正确的位置。这是错误之一。

为什么假设字体目录位于 homeFoods 而不是 /homeFoods/app/assets/ ？

应用程序.rb

config.assets.paths << Rails.root.join('app', 'assets', 'fonts')
config.assets.precompile += %w( .svg .eot .woff .ttf )

bootstrap.css

font-face {
 font-family: 'Glyphicons Halflings';
 src: url('/assets/glyphicons-halflings-regular.eot');
  src: url('/assets/glyphicons-halflings-regular.eot?#iefix') 
format('embedded-opentype'), url('/assets/glyphicons-halflings-regular.woff') format('woff'), url('/assets/glyphicons-halflings-regular.ttf') format('truetype'), url('/assets/glyphicons-halflings-regular.svg#glyphicons_halflingsregular') format('svg');}

我确实尝试过这种方法Bootstrap 3+Rails 4 - Certain Glyphicons not working，它曾经有效，但现在不行了。我不知道为什么它有效，因为他指定的路径不正确，供应商不包含字体文件夹。

   config.assets.paths << "#{Rails}/vendor/assets/fonts"

【问题讨论】：

有助于在页面加载时查看控制台错误。
我提到的错误就是问题所在。加载页面时它不显示我的图标！
祝你好运。

【解决方案1】：

在这种情况下，我只需创建一个新文件 icons.css.scss 并在其中使用 asset-url 助手。例如：

@font-face { font-family: 'EntypoRegular'; src: asset-url('fontello.eot'); src: asset-url('fontello.eot?#iefix') format('embedded-opentype'), asset-url('fontello.ttf') format('truetype'), asset-url('fontello.woff') format('woff'), asset-url('fontello.svg#EntypoRegular') format('svg'); }

接下来我通过添加//= require icons 将此文件包含在我的application.css.scss 中。希望对您有所帮助。
