我在我的应用程序错误TS2339中收到错误：属性'过滤器'在类型'Observable'上不存在我试图导入恶意的东西但它没有用 . 我的组件ts文件

import { Component, OnInit } from '@angular/core';
  import {
  Router,
  ActivatedRoute,
  NavigationEnd,
  Params,
  PRIMARY_OUTLET
} from '@angular/router';
import 'rxjs/add/operator/filter';

  ngOnInit() {
    const ROUTE_DATA_BREADCRUMB: string = 'breadcrumb';
    //subscribe to the NavigationEnd event
    this.router.events
      .filter(event => event instanceof NavigationEnd)
      .subscribe(event => {
        //set breadcrumbs
        let root: ActivatedRoute = this.activatedRoute.root;
        this.breadcrumbs = this.getBreadcrumbs(root);
        console.log(this.breadcrumbs);
      });
  }

我的package.json

"dependencies": {
    "@agm/core": "^1.0.0-beta.5",
    "@angular/animations": "^6.1.8",
    "@angular/common": "^6.0.3",
    "@angular/compiler": "^6.0.3",
    "@angular/core": "^6.0.3",
    "@angular/forms": "^6.0.3",
    "@angular/http": "^6.0.3",
    "@angular/platform-browser": "^6.0.3",
    "@angular/platform-browser-dynamic": "^6.0.3",

    "bootstrap3": "^3.3.5",
    "core-js": "^2.5.4",
    "jquery": "^3.3.1",
    "rxjs": "^6.0.0",
    "zone.js": "^0.8.26"
  },

    愚蠢的错误只需要管道

    ngOnInit() {
    this.router.events.pipe(
        filter(event => event instanceof NavigationEnd)
    ).subscribe(event => {
    //set breadcrumbs
    let root: ActivatedRoute = this.activatedRoute.root;
    this.breadcrumbs = this.getBreadcrumbs(root);
    console.log(this.breadcrumbs);
  });
}

    并导入

    import { filter } from 'rxjs/operators';
