vue-cli中怎么配置sass

vue-cli 新建项目初始化完毕后。
1.安装对应依赖node模块：

npm install node-sass --save-dev
npm install sass-loader --save-dev

2.打开webpack.base.config.js在loaders里面加上红色标注的代码

rules: [
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: vueLoaderConfig
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        include: [resolve('src'), resolve('test')]
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        query: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.scss$/,
        loaders: ["style", "css", "sass"]
      }
    ]
  }

3.在用scss要这样写

<style scoped lang="scss" >
.search_box {
  padding-left: 20px;
  padding-right: 20px;
}
</style>
