使用ionic3,angularfire2 v5

TypeError:Object(...)不是SwitchMapSubscriber._next上的SwitchMapSubscriber.project(http:// localhost:8100/build/vendor.js:73935:76)的函数(http:// localhost:8100/build/vendor.js:61778:27)在SwitchMapSubscriber.Subscriber.next(http:// localhost:8100/build/vendor.js:20750:18)的RefCountSubscriber.Subscriber._next(http:// localhost:8100/build/vendor.js:20786:26)在Subject.next(http:// localhost:8100/build/vendor)的RefCountSubscriber.Subscriber.next(http:// localhost:8100/build/vendor.js:20750:18). js:23237:25)在ConnectableSubscriber.Subscriber._next(http:// localhost:8100/build/vendor.js:20786:26)的ConnectableSubscriber.Subscriber.next(http:// localhost:8100/build/vendor. js:20750:18)在Asification.observe(http:// localhost:8100/build/vendor.js:51866:50)的AsyncAction.DelaySubscriber.dispatch(http:// localhost:8100/build/vendor.js: 76246:40)

任何人都可以帮助我服务器端渲染（SSR），如果我从 webpack 中删除样式加载器，就会出现 CSS 代码问题。

webpack:///./node_modules/style-loader/dist/runtime/injectStylesIntoStyleTag.js?:93 var style = document.createElement('style'); ^

ReferenceError：文档未在 addStyle (webpack:///./node_modules/style-loader/dist/runtime/injectStylesIntoStyleTag.js?:93:15) 处定义/dist/runtime/injectStylesIntoStyleTag.js?:208:13) 在 moduleToDom (webpack:///./node_modules/style-loader/dist/runtime/injectStylesIntoStyleTag.js?:81:18) 在 module.exports (webpack: ///./node_modules/style-loader/dist/runtime/injectStylesIntoStyleTag.js?:239:25) 在 eval (webpack:///./src/App.css?:15:14) 在 Object../ src/App.css (C:\reactjs\ssr-demo\server-build\index.js:1:20922) 在 (C:\reactjs\ssr-demo\server-build\index.js:1:172 ）在 eval (webpack:///./src/App.js?:4:66) 在 Module../src/App.js (C:\reactjs\ssr-demo\server-build\index.js: 1:21877) 在 (C:\reactjs\ssr-demo\server-build\index.js:1:172)

我已成功更新 angularfire 5.0.0.rc 8 和 firebase 5.0.2，没有错误模块。我想我要做的最后一件事是更改此代码以检索所有数据

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { IonicPage } from 'ionic-angular/navigation/ionic-page';
import { Observable } from 'rxjs';
import 'rxjs/add/operator/map';
import { Note } from '../../model/note/note.model';
import { NoteListService } from '../../services/note-list.service';

@IonicPage()
@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  noteList: Observable<Note[]>

  constructor(public navCtrl: NavController, private noteListService: NoteListService) {
    this.noteList = this.noteListService.getNoteList()
      .snapshotChanges()
      .map(
        changes => {
          return changes.map(c => ({
            key: c.payload.key, ...c.payload.val() …

socket.on('private-message', function(data){
        console.log("Sending: " + data.content + " to " + data.username);
        console.log(clients[data.username].socket.join(', '));
        if (clients[data.username]){    
            io.sockets.connected[clients[data.username].socket].emit("add-message", data);
        } else {
            console.log("User does not exist: " + data.username);
        }
    });

这段代码可以正常工作，但是我想要的是，我想使用其套接字ID发送多个连接到套接字的已连接客户端。

io.sockets.connected [reciver.socketid] .emit（“ add-message”，data）;

有什么办法可以写接收者socket.id组吗？我不想使用for循环。
