安装 rails 失败，"failed to build gem native extension"

Question

我刚刚在 windows 10 x64 上安装了 ruby 和 gem，我检查过它们都已安装。当我尝试安装 rails 时，它在一段时间后失败了。

Answer 1

我使用 wsl 解决了这个问题。安装过程解释 here. I also had to use this 以在 windows 10 build 16299.192（设置 > 系统 > 关于）上启用 wsl。在我安装了所有东西之后，我运行 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本机扩展。

sudo apt-get update
sudo apt-get install build-essential
