vue-cli sass安装

1.安装相关模块：

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：

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"]
      },
      {
        test: /.(woff2?|eot|ttf|otf)(?.*)?$/,
        loader: 'url-loader',
        query: {
          limit: 10000,
          name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
        }
      }
    ]
  }

3.在.vue文件中使用

<style lang='scss' scoped>

// 填加自己的内容

</style>
