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

Question

I'm trying to get my application to run with the new RC7 of angular but i cant seem to be able to get it done, as the console shouts: 我正在尝试让我的应用程序与新的angular7 RC7一起运行，但由于控制台喊叫声，我似乎无法完成它：

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

And when this somehow disappears, this pops up: 而当这种莫名其妙消失，这会弹出：

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

Looks like the implementation changed, and mine isn't updated although i npm install ed everything from scratch, update my package.json as follows: 看起来实现方式已更改，尽管我的npm install从头开始npm install所有内容，但我的更新没有更新，请按如下所示更新我的package.json ：

index.html: (I have also tried refering to unpkg.com for the packages, no success) index.html ：（我也尝试过参考unpkg.com来获取软件包，但没有成功）

Any idea how to fix this? 任何想法如何解决这个问题？

NOTEs : 注意事项 ：

As per package.json, you are using Angular2.0.0 You don't need angular2-polyfills.js 根据package.json，您正在使用Angular2.0.0。您不需要angular2-polyfills.js
Remove "angular2": "2.0.0-beta.17" , from package.json 从package.json中删除“ angular2”：“ 2.0.0-beta.17”
Remove angular2-polyfills.js from index.html 从index.html删除angular2-polyfills.js
```
 <script src="node_modules/angular2/bundles/angular2-polyfills.js"></script> 
```

Infact, if you have angular2 folder under node_modules then delete that folder. 逸岸，如果你有下node_modules angular2文件夹，然后删除该文件夹。 latest angular2 packages will be available in @angular folder under node_modules . 最新的angular2软件包将在node_modules下的@angular文件夹中提供。
