npm 启动时的 ASP.NET 样板 Angular 项目错误

Question

我使用基于.Net Core 和Angular 的ASP.NET Boilerplate Framework。我一步一步地遵循this page 中的指令，但是当我运行 npm start 时，我收到以下错误消息：

 @ ./src/polyfills.ts 36:0-27
 @ multi ./src/polyfills.ts

这是我的框架版本：

npm -v // 3.10.10
node -v // 6.11.3
tsc -v //2.5.3
ng -v // @angular/core 4.4.4
angular-cli version in `package.json` : //@angular/cli": "^1.3.2"

我认为这与角度版本或打字稿版本有关。对吗？ 我应该怎么做才能解决这个问题？

Answer 1

将此添加到angular/package.json：

"web-animations-js": "^2.3.1"

在angular/src/polyfills.ts中取消注释：

import 'web-animations-js';

Answer 2

此问题已在 v3.2 版本中得到修复。获取最新版本。
