node_modules/rxjs/Rxamp;amp;quot;' has no exported member 'of'

按照官方文档写代码

import { Injectable } from '@angular/core';
import { Observable, of } from 'rxjs';
//import { Observable } from 'rxjs/Observable';
//import 'rxjs/add/observable/of';
import {Hero} from './hero';
import {HEROS} from './mock-heros';@Injectable()
export class HeroService {constructor() { }//获取英雄列表getHeros(): Observable<Hero[]> {return of(HEROS);}}

但Angular编译失败,报错

后来在rxjs帮助文档中找到解决办法;

http://reactivex.io/rxjs/manual/installation.html

正确代码如下:

import { Injectable } from '@angular/core';
//import { Observable, of } from 'rxjs';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';
import {Hero} from './hero';
import {HEROS} from './mock-heros';@Injectable()
export class HeroService {constructor() { }//获取英雄列表getHeros(): Observable<Hero[]> {return Observable.of(HEROS);}}
