如果你有一个叫做scaffold。css的文件。Scss，那么就有可能覆盖您在其他文件中所做的所有自定义操作。我把那个文件注释掉了，突然之间一切都正常了。如果那个文件里没有什么重要的东西，你还不如把它删掉!

这里有一个转折:

你应该把所有的字体放在app/assets/fonts/中，因为它们在默认情况下会在登台和生产中被预编译——当推送到heroku时，它们会被预编译。 默认情况下，放置在vendor/assets中的字体文件不会在登台或生产时预编译-它们将在heroku上失败。源!

我坚信把厂商字体放到厂商/资产/字体中 这比把它们放到app/assets/字体中更有意义。与 这两行额外的配置对我来说工作得很好 Rails 4):

app.config.assets.paths << Rails.root.join('vendor', 'assets', 'fonts')  
app.config.assets.precompile << /\.(?:svg|eot|woff|ttf)$/

我还在rails 4.0.0上测试了它。实际上，最后一行已经足够从供应商文件夹安全预编译字体了。花了几个小时才弄明白。希望它能帮助到某人。

If your Rails version is between > 3.1.0 and < 4, place your fonts in any of the these folders: app/assets/fonts lib/assets/fonts vendor/assets/fonts For Rails versions > 4, you must place your fonts in the app/assets/fonts folder. Note: To place fonts outside of these designated folders, use the following configuration: config.assets.precompile << /\.(?:svg|eot|woff|ttf)\z/ For Rails versions > 4.2, it is recommended to add this configuration to config/initializers/assets.rb. However, you can also add it to either config/application.rb , or to config/production.rb Declare your font in your CSS file: @font-face { font-family: 'Icomoon'; src:url('icomoon.eot'); src:url('icomoon.eot?#iefix') format('embedded-opentype'), url('icomoon.svg#icomoon') format('svg'), url('icomoon.woff') format('woff'), url('icomoon.ttf') format('truetype'); font-weight: normal; font-style: normal; } Make sure your font is named exactly the same as in the URL portion of the declaration. Capital letters and punctuation marks matter. In this case, the font should have the name icomoon. If you are using Sass or Less with Rails > 3.1.0 (your CSS file has .scss or .less extension), then change the url(...) in the font declaration to font-url(...). Otherwise, your CSS file should have the extension .css.erb, and the font declaration should be url('<%= asset_path(...) %>'). If you are using Rails > 3.2.1, you can use font_path(...) instead of asset_path(...). This helper does exactly the same thing but it's more clear. Finally, use your font in your CSS like you declared it in the font-family part. If it was declared capitalized, you can use it like this: font-family: 'Icomoon';

我在Rails 4.2 (ruby 2.2.3)上遇到了这个问题，不得不编辑字体很棒的_paths。SCSS部分删除对$fa-font-path的引用并删除前导正斜杠。以下是破碎的:

@font-face {
  font-family: 'FontAwesome';
  src: font-url('#{$fa-font-path}/fontawesome-webfont.eot?v=#{$fa-version}');
  src: font-url('#{$fa-font-path}/fontawesome-webfont.eot?#iefix&v=#{$fa-version}') format('embedded-opentype'),
    font-url('#{$fa-font-path}/fontawesome-webfont.woff2?v=#{$fa-version}') format('woff2'),
    font-url('#{$fa-font-path}/fontawesome-webfont.woff?v=#{$fa-version}') format('woff'),
    font-url('#{$fa-font-path}/fontawesome-webfont.ttf?v=#{$fa-version}') format('truetype'),
    font-url('#{$fa-font-path}/fontawesome-webfont.svg?v=#{$fa-version}#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

以及以下工作:

@font-face {
  font-family: 'FontAwesome';
  src: font-url('fontawesome-webfont.eot?v=#{$fa-version}');
  src: font-url('fontawesome-webfont.eot?#iefix&v=#{$fa-version}') format('embedded-opentype'),
    font-url('fontawesome-webfont.woff2?v=#{$fa-version}') format('woff2'),
    font-url('fontawesome-webfont.woff?v=#{$fa-version}') format('woff'),
    font-url('fontawesome-webfont.ttf?v=#{$fa-version}') format('truetype'),
    font-url('fontawesome-webfont.svg?v=#{$fa-version}#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

另一种方法是简单地删除插入的$fa-font-path后面的正斜杠，然后将$fa-font-path定义为一个空字符串或带正斜杠的子目录(根据需要)。

记得根据需要重新编译资产并重新启动服务器。例如，在乘客设置中:

prompt> rake assets:clean; rake assets:clobber
prompt> RAILS_ENV=production RAILS_GROUPS=assets rake assets:precompile
prompt> service passenger restart

然后重新加载浏览器。

如果你有一个叫做scaffold。css的文件。Scss，那么就有可能覆盖您在其他文件中所做的所有自定义操作。我把那个文件注释掉了，突然之间一切都正常了。如果那个文件里没有什么重要的东西，你还不如把它删掉!

只需要把你的字体放在app/assets/fonts文件夹中，并在app开始使用application.rb中编写代码时设置自动加载路径

config.assets.paths << Rails.root。加入("app"， "assets"， "fonts") 而且

然后在css中使用以下代码。

@font面{

 font-family: 'icomoon';
 src: asset-url('icomoon.eot');
 src: asset-url('icomoon.eot') format('embedded-opentype'),
      asset-url('icomoon.woff') format('woff'),
      asset-url('icomoon.ttf') format('truetype'),
      asset-url('icomoon.svg') format('svg');
 font-weight: normal;
 font-style: normal;

}

试一试。

谢谢
