Angular2无法更新到RC7 - zone.js &reflect-metadata

Angular2 Failing to update to RC7 - zone.js & reflect-metadata

本文关键字：zone js reflect-metadata RC7 更新 Angular2      更新时间：2023-09-26

我正试图让我的应用程序运行与新的RC7的角，但我似乎不能得到它完成，因为控制台喊道:

Promise rejection: Zone.assertZonePatched is not a function      angular2-polyfills.js:489

当不知怎么的消失时，这个会弹出:

Reflect.getMetadata is not a function (..)                                core.umd.js:472

看起来实现改变了，我的没有更新，虽然我npm install从头开始，更新我的package.json如下:

index.html:(我也试着从unpkg.com获取包，没有成功)

你知道怎么解决这个问题吗?

提前感谢!:)

注释:

  • 按包计算。你不需要angular2 .js
  • 删除"angular2": "2.0.0-beta. "17",从 package.json

  • 删除 angular2-polyfills.js 与 index . html 

    <script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>

事实上，如果你在node_modules下有angular2文件夹，那么删除该文件夹。最新的angular2包将在node_modules下的@angular文件夹中提供。
