的Heroku：ActionController的:: RoutingError（无路由匹配[GET]“/fonts/glyphicons-halflings-regular.ttf）

Question

，我发现了以下错误在Heroku的：

ActionController::RoutingError (No route matches [GET] "/fonts/glyphicons-halflings-regular.ttf) 

当服务器尝试找到引导的halflings images来自供应商的资产：

当我用彪马和福尔曼在本地运行的应用程序，那么它的那些半身人的图像显示工作正常

Heroku的日志如下所示：

这些半身人可以在两个文件夹在我的项目中找到： vendor/assets/bower_components/bootstrap/dist/fonts vendor/assets/bower_components/bootstrap/fonts

除了这些半身人的图像，应用程序工作正常：

我以前删除public/assets目录提交并重新部署到Heroku上，这解决了我的大问题https://stackoverflow.com/a/28681947/2048391感谢史蒂夫。旧版问题（当导航栏没有出现时）中的错误信息与此类似，所以这个问题也可能与资产有关。

如果您的问题听起来很熟悉，那么请删除一行。非常感谢:-)

已部署到Heroku上的代码可以在GitHub

Answer 1

发现你有几个问题在这里。

• 字体资产不在链轮已知的路径中，因此当资产编译处于打开状态（即生产）时，它们将不会被提供。
• 即使您固定资产编译，您也正在使用bootstrap.css的静态版本，因此无法将字体资产的路径设置为与Rail放置它们的位置相匹配。

解决方案：

1. 使用官方的引导，萨斯凉亭包，这将引导编译使用正确的字体路径。

   安装亭子，青菜和删除香草引导：

   bower uninstall bootstrap --save 
   bower install bootstrap-sass --save 
   

2. 移动application.css到application.css.scss。在mainfest部分之后添加以下几行。

   $icon-font-path: "bootstrap-sass/assets/fonts/bootstrap/"; 
   @import "bootstrap-sass/assets/stylesheets/bootstrap-sprockets"; 
   @import "bootstrap-sass/assets/stylesheets/bootstrap"; 
   

   因为非sass的bootstrap版本被删除，您还必须确保删除此行。

   *= require bootstrap/dist/css/bootstrap 
   

3. 将出售资产路径添加到application.rb，以便rails可以编译和提供它们。

   您的application.rb需要更新，以便Rails知道资产的存在位置。每官方引导，SASS文件（https://github.com/twbs/bootstrap-sass#c-bower）：

   # Bower asset paths 
   root.join('vendor', 'assets', 'bower_components').to_s.tap do |bower_path| 
       config.sass.load_paths << bower_path 
       config.assets.paths << bower_path 
   end 
   # Precompile Bootstrap fonts 
   config.assets.precompile << %r(bootstrap-sass/assets/fonts/bootstrap/[\w-]+\.(?:eot|svg|ttf|woff2?)$) 
   # Minimum Sass number precision required by bootstrap-sass 
   ::Sass::Script::Number.precision = [8, ::Sass::Script::Number.precision].max 
   

这应该可以解决这个问题，你glyphicons应该现在载入。
