未找到Webpack优化构造函数

我正在测试windowspack系统上的webpack和node.js。我有此脚本“webpack.config.js”未找到Webpack优化构造函数

var debug = process.env.NODE_ENV !== "production"; 
var webpack = require('webpack'); 

module.exports = { 
    context: __dirname, 
    devtool: debug ? "inline-sourcemap" : null, 
    entry: "./js/scripts.js", 
    output: { 
    path: __dirname + "/js", 
    filename: "scripts.min.js" 
    }, 
    plugins: debug ? [] : [ 
    new webpack.optimize.DedupePlugin(), 
    new webpack.optimize.OccurenceOrderPlugin(), 
    new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }), 
    ], 
};

当我打电话的WebPack与生产标签我收到以下错误：

C:\Users\srussell\Desktop\GitHub\nodejsTest\webpack.config.js:14 
    new webpack.optimize.OccurenceOrderPlugin(), 
    ^

TypeError: webpack.optimize.OccurenceOrderPlugin is not a constructor 
    at Object.<anonymous> (C:\Users\srussell\Desktop\GitHub\nodejsTest\webpack.config.js:14:5) 
    at Module._compile (module.js:570:32) 
    at Object.Module._extensions..js (module.js:579:10) 
    at Module.load (module.js:487:32) 
    at tryModuleLoad (module.js:446:12) 
    at Function.Module._load (module.js:438:3) 
    at Module.require (module.js:497:17) 
    at require (internal/module.js:20:19) 
    at requireConfig (C:\Users\srussell\AppData\Roaming\npm\node_modules\webpack\bin\convert-argv.js:96:18) 
    at C:\Users\srussell\AppData\Roaming\npm\node_modules\webpack\bin\convert-argv.js:109:17

然而，当我从节点控制台运行console.log(require('webpack')); cmd它显示我已安装webpack并且优化功能和方法可用。
