我刚刚在Windows 10 x64上安装了ruby和gem，我检查了它们都已安装。当我尝试安装rails时，它会在一段时间后失败。

我使用wsl解决了这个问题。安装过程解释为here。我还必须使用this在Windows 10 build 16299.192（设置＆gt; system＆gt; about）上启用wsl。在我安装完所有内容后，我运行了sudo apt-get install nodejs和gem install rails。在此之后，我可以运行演示（wsl> rails new demo，wsl> cd demo，wsl> rails server）。

您需要构建工具来构建原生扩展。
sudo apt-get update
sudo apt-get install build-essential
