这个简单的演示有一个错误 https://docs.nestjs.com/techniques/http-module

import { Get, Controller, HttpService } from '@nestjs/common';
import { AxiosResponse } from 'axios'
import { Observable } from 'rxjs'
@Controller()
export class AppController {
  constructor(private readonly http: HttpService) {}
  @Get()
  root(): Observable<AxiosResponse<any>>  {
    return this.http.get('https://api.github.com/users/januwA');
  }
}

我该怎么办？
