Angular 6 and AngularFire2 RxJS Error

问题

I want to create a new Angular 6 App with AngularFire 2. Although I followed the tutorial, I get a version error.

AngularFire2 Setup Tutorial: https://github.com/angular/angularfire2/blob/master/docs/install-and-setup.md

Even though I only tried to use an Observable as seen in the tutorial I get the following error:

ERROR in node_modules/angularfire2/angularfire2.d.ts(3,10): error TS2305: Module '"/Users/tarek/Documents/Development/web_app/apphoven-web/node_modules/rxjs/Subscription"' has no exported member 'Subscription'.

node_modules/rxjs/Subscription.d.ts(1,15): error TS2307: Cannot find module 'rxjs-compat/Subscription'.

Am I correct that AngularFire 2 does not support Angular 6? Because it's not written anywhere. And I don't think it's a good idea to downgrade to the old Angular CLI... So, what can I do?

npm install --save rxjs-compat

npm install --save rxjs-compat

回答3:

Add following code in polyfills.ts (window as any).global = window;

回答4:

npm install --save @rxjs-compat@5.0

回答5:

You've to fix your Rxjs imports. There are some changes in the use of rxjs from v6 onwards. so, Kindly import the observable as below

import { Observable } from 'rxjs';

instaed of import { Observable } from 'rxjs/Observable';

Hope this will fix your issue. Happy coding :)

回答6:

npm i --save rxjs-compat helps!
