vue 配置scss流程

引入相关的node包

npm install --save style-loader sass-loader node-sass file-loader

安装好之后，为了可以在.vue和.scss中使用，需要在vue.config.js中配置对应的解析器

module.exports = {
  entry: ['./src/entry.js'],
  output: {
    path: __dirname,
    filename: 'build/main.js'
  },
  resolve: {
    alias: {
      'vue': 'vue/dist/vue.js'
    }
  },
  module: {
    loaders: [{
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
            scss: 'style-loader!css-loader!sass-loader'
          }
        }
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },{
        test: /\.css$/,
        loader: ['style-loader', 'css-loader']
      }, {
        test: /\.scss$/,
        loader: ['style-loader', 'css-loader', 'sass-loader']
      }, {
        test: /\.(png|jpg|jpeg|gif|bmp)$/,
        loader: ['file-loader?limit=7000&name=build/assets/[name].[ext]']
      }
    ]
  }
};```
