第一次使用rails。我安装了一切。我试图使应用程序工作并执行服务器但它仍然失败。这就是我得到的。如果有人可以帮助你，谢谢。 我在Windows 10操作系统上。

答案 0 :(得分：-2)
首先，您是否写过bundle install？
其次，你确定要'宝石'吗？
在我看来，你应该安装ubuntu（非常简单易用，请参阅：https://www.codecademy.com/命令行教程）和代码。要安装ubuntu，您可以下载虚拟机（免费）等内容来创建虚拟机。
为什么我告诉你这个？因为Windows上的代码真的很难。你会遇到很多问题。
我已尝试安装新项目，但我的rails会自动执行bundle install，抱歉：s
