egghead.io - Angular，Webpack和UglifyJs教程 - 意外令牌

我想解决我的问题。我正在做egghead.io中的教程，我无法运行npm run build。egghead.io - Angular，Webpack和UglifyJs教程 - 意外令牌

下面的代码是在终端控制台

ERROR in bundle.js from UglifyJs 
SyntaxError: Unexpected token: operator (>) [bundle.js:83,72]

所有者可以运行具有的WebPack和uglifyJs巴贝尔的错误，但我不能这样做。所以Idk，如果ES6和Uglify-Js之间存在问题，就像大多数条目对此错误所说的那样。

这是我webpack.config.js：

var webpack = require('webpack'); 

var config = { 
    context: __dirname + '/app', 
    entry: './index.js', 
    output:{ 
    path: __dirname + '/app', 
    filename: 'bundle.js' 
    }, 
    plugins:[ 
    new webpack.DefinePlugin({ 
     ON_TEST: process.env.NODE_ENV =='test' 
    }) 
    ], 
    module:{ 
    loaders:[ 
     { test: /\.js$/, loader: 'babel-loader', exclude: /node_modules/}, 
     { test: /\.html$/, loader: 'raw-loader', exclude: /node_modules/}, 
     { test: /\.css$/, loader: 'style-loader!css-loader', exclude: /node_modules/}, 
     { test: /\.styl$/, loader: 'style-loader!css-loader!stylus-loader', exclude: /node_modules/} 
    ] 
    } 
} 

if (process.env.NODE_ENV === 'production'){ 
    config.output.path = __dirname + '/dist'; 
    config.plugins.push(new webpack.optimize.UglifyJsPlugin()); 
} 

module.exports = config;

，这是我的package.json文件：

    "name": "webpack-angular", 
    "version": "1.0.0", 
    "description": "Example of using webpack",

    },

    "webpack": "fulls1z3/webpack#v2.1.0-beta.27-harmony",

    } 
}

什么想法，请？

亲切的问候，

我自己修复了它

我在根文件夹中创建了一个.babelrc文件。

{ 
    presets:["es2015"] 
}

我已经通过npm安装了“babel-preset-es2015”包。

最后，我曾与源地图的问题，然后我把财产config.plugins.push(new webpack.optimize.UglifyJsPlugin({ sourceMap: true }))，其问题是在https://github.com/shama/webpack-stream/issues/81
