这里有更新过的代码可以参考

发现问题了，这个视频是webpack 2.5 之前的，现在webpack 使用不能这样用，需要更新，但是不知道这个视频的应该如何更新，更新成下面这样，报错，求解现在应该如何写呢

更新如下：

module.exports = {

  entry: {

     index: './js/index'

  },

  output: {

      filename: '[name].js' 

  },

  devtool: 'source-map',

    resolve: {

        extensions: ['.js'] 

    },

    module: {

        rules: [{

            test: /\.js$/, 

            exclude: /node_modules/, 

            use: [{

                loader: 'babel', 

                options: {

                    presets: ['es2015'] ////按照最新的 ES6 语法规则去转换

                }

            }]

        }]

    }

}

错误如下：

internal/streams/legacy.js:59

      throw er; // Unhandled stream error in pipe.

      ^

Error: Entry module not found: Error: Can't resolve 'babel' in 'F:\qianduan_dir\00program\JQuery\shudu\src'

BREAKING CHANGE: It's no longer allowed to omit the '-loader' suffix when using loaders.

                 You need to specify 'babel-loader' instead of 'babel',

                 see https://webpack.js.org/migrate/3/#automatic-loader-module-name-extension-removed

现在是需要使用 options 了么？
