我正在使用 angular2-JWT 介绍 angular2 和 json Web 令牌。我在实例化 AuthHttp 类的对象时遇到了一些问题

这是我的 app.module.ts

import { NgModule }       from '@angular/core';
import { BrowserModule }  from '@angular/platform-browser';
import { HTTP_PROVIDERS, Http } from '@angular/http';
import { AuthHttp, AuthConfig, AUTH_PROVIDERS, provideAuth } from 'angular2-jwt';

import { AppComponent }   from './app.component';
import { IndexComponent } from './Components/Index/index.component';
import { AuthService }   from './Services/auth.service';

import { routing } from './app.routing';

@NgModule({
  imports: [
    BrowserModule,
    routing,
  ],
  declarations: [
    AppComponent,
    IndexComponent,
  ],
  providers: [
    AuthService,
    AuthHttp,
    provideAuth({
        headerName: 'Authorization',
        headerPrefix: 'bearer',
        tokenName: 'token',
        tokenGetter: (() => localStorage.getItem('id_token')),
        globalHeaders: [{ 'Content-Type': 'application/json' }],
        noJwtError: true
    })
  ]
  bootstrap: [AppComponent]
})

export class AppModule { }

和我的 auth.service.ts

import { Injectable } from '@angular/core';

@Injectable()
export class AuthService {

  constructor(public authHttp: AuthHttp) {}

}

当我将构造函数添加到我的服务时，我得到以下错误

你失踪了吗 import { AuthHttp } from 'angular2-jwt';

在你的 auth.service.ts 中？
