解决方案
这是Angular CLI 1.0.0-beta.11-webpack.8依赖项错误；您可以通过以下方法解决应用程序中的错误:
npm install awesome-typescript-loader@2.2.1 --save-dev
或者，您可以使用依赖项修复程序在本地重建Angular CLI ./p>
Updating my Angular 2 CLI project from 1.0.0-beta.11-webpack.2 to 1.0.0-beta.11-webpack.8 via ng init, and running ng serve results in the following error:
