Ruby on rails 未初始化的常量链轮：：引导

当我试图用命令预编译我的资产时，我会遇到这个错误 “rake资产：预编译” 当我安装gem“涡轮链轮轨道”时，我开始出现此错误 我正在使用rails 4.0.0和ruby 2.2.3。 谁能帮帮我吗

我有Gem-Uglifier-v2.7.2

当我在Gemfile中删除gem-turbo-sprockets-rails时，该命令运行良好，但在我的视图中，我的css和javascript没有运行

rails 4修复了turbo-sprockets-rails解决的资产管道问题。您应该能够将其从资产管道中删除，并且在预编译资产时一切正常。

您有

Gem uglifier

安装吗？用Gemfile更新您的问题谢谢我已经解决了我的问题。我在Windows操作系统上工作。我只是在linux发行版（LinuxMint17）上预编译应用程序，然后运行它。但我不知道为什么，因为我什么也没有添加另一个宝石
