我是Angular的新手。我从https://github.com/angular/quickstart（app文件夹位于src文件夹内）下载了Angular 2快速启动模板，然后使用VS代码修改packages.json内容，并手动创建组件/服务/等应用程序文件夹内的文件/文件夹。基于我在网上找到的教程。当我使用npm start启动应用程序时，该应用程序运行良好，但我坚持创建DIST文件夹，我需要将该应用程序的缩小版本上传到Azure Web应用程序。每当我从我的角度2项目的根目录运行ng build，我得到下面的错误：ng服务错误：“无法读取未定义的属性”0“
Cannot read property '0' of undefined
TypeError: Cannot read property '0' of undefined
