Glyphicons在生产轨道中没有正确预编译

使用Rails 4,我遇到了一个问题,即Bootstrap中的glyphicons没有被正确预编译.生成以下内容:

started GET "/assets/glyphicons-halflings-white-ed38e147e3f6e976c0a7ad59e4d628f3.png" for          127.0.0.1 at 2014-01-13 18:41:25 -0500

Completed 404 Not Found in 17ms (Views: 3.4ms | ActiveRecord: 8.0ms)
Completed 404 Not Found in 17ms (Views: 3.4ms | ActiveRecord: 8.0ms)

它在开发中工作正常.如果我config.assets.compile = true在production.rb中设置它似乎工作正常 - 但我理解基于这个SO问题是非常糟糕的: 资产:precompile生成的文件与stylesheet_link_tag(缺少摘要)在最小的rails 4中生成的url不匹配现场

在Rails 3.2中,这对我来说不是问题.

任何帮助将不胜感激!
