npm rebuild node-sass记录

报错原因

node.js从8升级到了11，再次运行原有项目时提示如下

Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 11.x

Found bindings for the following environments:
  - Windows 64-bit with Node.js 8.x

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to download the binding for your current environment.

解决方法

在项目的目录下运行终端，执行下面的指令

npm install --save-dev rebuild-node-sass node-sass
