今天我正在将Angular RC 6应用程序更新为新发布的最终版本。一切都运转良好，但是我和Protractor有问题。我收到以下错误：
server.listen(port, opt_host, function() {
TypeError: Cannot read property 'listen' of undefined
我从该应用程序的先前版本更改的是package.json文件。我猜这是一个配置问题，但我似乎无法找到有关Protractor配置的任何改变。
此外，我在此应用程序中使用了webpack - 我不知道它是否与webpack有关。也许某人在webpack和Angular 2 Final版本上遇到了一些问题。

更新 - 进一步测试
出于测试目的，我使用angular-cli和Webpack创建了一个新项目。我这样做是为了验证我的应用程序中的配置是否有任何问题。我没有注意到任何与众不同的东西。我唯一尝试过的是将protractor更新为最新版本4.0.5。不幸的是，我得到了相同的结果：Cannot read property 'listen' of undefined
