2.全局安装vue-cli

3.创建一个webpack 的项目

vue init webpack#1.0 my-project(安装1.0)

4.安装依赖

cd my-project
npm install

安装完以后可以看到项目中多了 node_modules这个文件夹

5.安装sass的依赖包

npm install --save-dev sass-loader
//sass-loader依赖于node-sass
npm install --save-dev node-sass

安装完后的package.json目录为下

6.修改style标签

打开app.vue,修改style为

<style lang="scss">

style中 添加内容

$color:red;p {color:$color}

进行测试。
ps:引入的scss文件必须带后缀，否则报错，如下图
