Angular2 Failing to update to RC7 - zone.js & 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:

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

And when this somehow disappears, this pops up:

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

Looks like the implementation changed, and mine isn't updated although i npm installed everything from scratch, update my package.json as follows:

{
  "name": "angular2-quickstart",
  "version": "1.0.0",
  "scripts": {
    "build": "webpack",

  },
  "devDependencies": {
    "ts-loader": "^0.8.2"
  }
}

index.html: (I have also tried refering to unpkg.com for the packages, no success)

</html>

Any idea how to fix this?

Thanks in advance! :)

You are installing Angular2.0(recent release packages) If you are looking for RC7 package, kindly refer to - http://stackoverflow.com/questions/39496055/which-angular-forms-version-for-angular-2-rc7/39496132#39496132 where I have shown RC7 packages with systemjs not webpack. — micronyks, Sep 17 '16 at 16:29
@micronyks Hey, updated my package.json, this still produces the same error, any ideas? — Kesem David, Sep 17 '16 at 16:35
@micronyks Yes, i have updated my package.json to `"@angular/XXX": "2.0.0-rc.7"` and did as the below answer suggested — Kesem David, Sep 17 '16 at 17:01

NOTEs:

As per package.json, you are using Angular2.0.0 You don't need angular2-polyfills.js
Remove "angular2": "2.0.0-beta.17", from package.json

Remove angular2-polyfills.js from index.html

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

Infact, if you have angular2 folder under node_modules then delete that folder. latest angular2 packages will be available in @angular folder under node_modules.

You're basically saying i should remove the dependency of angular2 from my `package.json` and just re-`npm i`? (updated my `package.json` dependencies to those with -rc.7) – Kesem David Sep 17 '16 at 16:35
And the angular2 package doesn't seem to exist inside @angular under node_modules :| – Kesem David Sep 17 '16 at 16:37
Clean node_modules folder and then run `npm install` it will give you packages inside @angular under node_modules. – Sanket Sep 17 '16 at 16:38
Once you got latest packages, remove `angular2-polyfills.js` from `index.html` and then run application. – Sanket Sep 17 '16 at 16:39
Should i keep the `angular2` dependency in the package.json or not? – Kesem David Sep 17 '16 at 16:40
Remove `"angular2": "2.0.0-beta.17",` from package.json – Sanket Sep 17 '16 at 16:41
THANK YOU! that worked!!, please note in your answer to remove this dependency from my package.json and ill accept and upvote it for the future readers ! :) – Kesem David Sep 17 '16 at 16:41

@sanket This doesn't work for me. I'm already using angular 2.0.0 and I don't use any polyfills.js in my package.json nor index.html. So I'm not sure why I'm still getting "Reflect.getMetadata is not a function" error. – Sam Sep 17 '16 at 17:39
@Sam can you please create new post with your details – Sanket Sep 17 '16 at 17:41
