我刚刚开始使用ruby on rails，在安装rails在控制台上执行许多命令之后，我尝试使用命令rails server运行rails服务器，但是收到有关不加载coffee-rails的错误，我尝试过命令gem install coffee-rails我得到了

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

    ERROR:  Error installing coffee-rails:

Answer 1

RubyGems 2.4.1不会在Windows 1.9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，请运行以下命令：

gem update --system 1.8.29

检查宝石版本：

gem -v
1.8.29

现在再次尝试你的命令：

gem install coffee-rails
