我有一个ASP.NET Core 2.0 / Angular模板应用程序。一切正常，直到我尝试发布。 我收到以下错误：
in ./ClientApp/boot.browser.ts
Module parse failed: E:\rootfolder\ClientApp\boot.browser.ts Unexpected token (14:19)
You may need an appropriate loader to handle this file type.
| const oldRootElem = document.querySelector('app');
| const newRootElem = document.createElement('app');
| oldRootElem!.parentNode!.insertBefore(newRootElem, oldRootElem);
| modulePromise.then(appModule => appModule.destroy());
| });
@ multi event-source-polyfill webpack-hot-middleware/client?path=__webpack_hmr&dynamicPublicPath=true ./ClientApp/boot.browser.ts
到目前为止，我已经完成了通常的谷歌搜索而没有运气。知道我应该在哪里看？这是一个使用VS 2017生成的角度模板的ASP.NET CORE 2.0应用程序。我在下面发布了package.json文件。我得到了相同的结果，我明确地调用了“donet publish”命令或者在VS 2017中按下发布按钮。

答案 0 :(得分：3)
通过将我的node / npm版本更新为最新推荐版本来解决此问题。 节点：v8.9.3 npm：5.5.1
