Question

我刚刚开始使用轨道上的红宝石，安装轨在控制台上执行许多命令后，我试图运行轨道服务器命令rails server，但得到一个关于不加载咖啡栏的错误，我试过了命令gem install coffee-rails我得到

gem install coffee-rails 
    Temporarily enhancing PATH to include DevKit...

Answer 1

Take a look at this answer - 他们似乎也有同样的烦恼，只好用化妆的旧版本。

Answer 2

RubyGems 2.4.1不会在Ruby 1.9.3及更早版本的Windows上构建本机扩展。

您需要将RubyGems降级到1.8.29。 为此运行以下命令：

gem update --system 1.8.29 

检查宝石版本：

gem -v 
1.8.29 

现在再次尝试您的命令：

gem install coffee-rails
