Rxjs 5：共享不是函数

Question

更新到 RxJs 5 后，我收到以下错误：

share is not a function

代码：

import { Observable } from 'rxjs/Observable';
import { Observer } from 'rxjs/Observer';
import { Injectable } from '@angular/core';
import { share } from "rxjs/operators/share";
import * as m from '../../models/app.models';

@Injectable()
export class SharedService {
    observable: Observable<any>;
    observer: Observer<any>;

    constructor() {
        var temp = Observable.create((observer: Observer<any>) => {
            this.observer = observer;
        });
        this.observable = temp.share(); <- Error here
    }

    broadcast(event: m.SharedEventModel) {
        this.observer.next(event);
    }

    on(eventName, callback) {
        return this.observable.filter((event) => {
            return event.Name === eventName;
        }).subscribe(callback);
    }
}

尝试按照http://stackoverflow.com/a/36174340/3955513进行 globalEvents

RxJs 版本：5.5.2

这是工作服务。

我已经从您用作参考的问题中更新了 Thierry Templier 的 plunker，Plunker

请注意，import { share } from "rxjs/operators";并非import { share } from "rxjs/operator/share";如其他地方所述。见lettable-operators.md

import { Injectable } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import { Observer } from 'rxjs/Observer';
import { share } from "rxjs/operators";   // lettable operator, tree-shakeable
import { filter } from "rxjs/operators";

@Injectable()
export class SharedService {
  observable: Observable<any>;
  observer: Observer<any>;

  constructor() {
    var temp = Observable.create((observer: Observer<any>) => {
      this.observer = observer;
    });
    this.observable = temp.pipe(share());
  }

  broadcast(event) {
    this.observer.next(event);
  }

  on(eventName, callback) {
    this.observable.pipe(filter(x => x.name === eventName))
      .subscribe(callback);
  }
}
