npm run dev 启动一个 Vue  项目报错：

Failed to compile with 1 errors 21:36:21
error in ./src/App.vue

Module build failed: Error: Node Sass does not yet support your current environment: Windows 64-bit with Unsupported runtime (72)
For more information on which environments are supported please see:
https://github.com/sass/node-sass/releases/tag/v4.9.3

可能是以前一直没用sass，升级了node没有连带升级相关组件，简单粗暴的卸载重装，解决问题。

npm uninstall node-sass

npm install node-sass
