我的应用程序出现错误 错误 TS2339:在类型“Observable”上不存在属性“filter” 我尝试导入各种东西,但没有起作用。 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",
