我正在尝试将我的 angular 9 应用程序升级到 angular 10 版本，但在升级后低于警告

rxjs\BehaviorSubject.js depends on rxjs-compat/BehaviorSubject

知道如何解决这个问题吗？

升级到 Angular 10 后，某些组件出现以下错误 -

ERROR TypeError: Class constructor EventEmitter_ cannot be invoked without 'new'
    at new ZoneAwareEventEmitter (index.js:34)
    at new GridComponent (index.js:6167)
    at createClass (core.js:21921)
    at createDirectiveInstance (core.js:21790)
    at createViewNodes (core.js:30281)
    at callViewAction (core.js:30597)
    at execComponentViewsAction (core.js:30516)
    at createViewNodes (core.js:30309)
    at callViewAction (core.js:30597)
    at execComponentViewsAction (core.js:30516)

导致此问题的代码 -

import { EventEmitter } from "@angular/core";

export class ZoneAwareEventEmitter extends EventEmitter {
    constructor(ngZone, isAsync = false) {
        super(isAsync);
        this.ngZone = ngZone;
    }
}

我错过了什么吗？

先谢谢您的帮助！
