vue 引入全局scss

1.安装依赖

npm install sass-loader@7.3.1 --save-dev    //新版本会报错
npm install node-sass --sava-dev
npm install sass-resources-loader --save-dev

2.在webpack.base.conf.js 添加配置参数

resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: {
      'vue$': 'vue/dist/vue.esm.js',
      '@': resolve('src'),
      'style':resolve('src/style')        //指向scss文件目录
    }
},

3.在main.js引入全局scss文件

import '@/style/index.scss'
