Question

我想解决我的问题。我在egghead.io上做了教程，我无法运行npm run build。

下一个代码是终端控制台中的错误

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

所有者可以使用webpack和uglifyJs运行babel，但我无法做到。所以，如果ES6和Uglify-Js之间存在问题，就像大多数条目都说这个错误一样。

这是我的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：

  }
}

请问任何想法？

亲切的问候，

我自己修理了

我在根文件夹中创建了一个.babelrc文件。

{
  presets:["es2015"]
}

我已经按照npm安装了“babel-preset-es2015”软件包。

最后我遇到了source-map的问题然后我放了属性config.plugins.push(new webpack.optimize.UglifyJsPlugin({ sourceMap: true }))，其问题位于https://github.com/shama/webpack-stream/issues/81
