我试图使用ngx-socket-io包，它在Angular.js中不起作用。有没有一个替代包可以在Angular中工作？
Moddule.js:

import { SocketIoModule, SocketIoConfig } from 'ngx-socket-io';
 
const config: SocketIoConfig = { url: 'http://localhost:8988', options: {} };
 
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    SocketIoModule.forRoot(config)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

ChatService.js

import { Injectable } from '@angular/core
import { Socket } from 'ngx-socket-io'
 
@Injectable()
export class ChatService {
 
    constructor(private socket: Socket) { }
 
    assign_biker(biker_id){

     this.socket.emit("assign_biker_order",{'biker_id:biker_id })

    }
}
