Question

我是角度js和打字稿的新手。我开始遵循文档中的angular2 英雄教程。但是我在教程的最后一节中遇到了一个错误，即 HTTP ，链接如下：

https://angular.io/docs/ts/latest/tutorial/toh-pt6.html

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import {AppRoutingModule} from './app-routing.module'

// Imports for loading & configuring the in-memory web api
import { InMemoryWebApiModule } from 'angular2-in-memory-web-api';
import { InMemoryDataService }  from './apis/in-memory-data.service';

import { HeroesComponent } from './heroes/heroes.component';
import { HeroDetailComponent } from './hero-detail/hero-detail.component';
import { AppmainComponent } from './appmain/appmain.component';
import { DashboardComponent } from './dashboard/dashboard.component';

import {HeroService} from "./hero.service";


@NgModule({
  declarations: [
    HeroesComponent,
    HeroDetailComponent,
    AppmainComponent,
    DashboardComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    AppRoutingModule,
    HttpModule,
    InMemoryWebApiModule.forRoot(InMemoryDataService)
  ],
  providers: [HeroService],
  bootstrap: [AppmainComponent]
})
export class AppModule { }

内存数据-service.ts

import { InMemoryDbService } from 'angular2-in-memory-web-api';
export class InMemoryDataService implements InMemoryDbService {
  createDb() {
    let heroes = [
      {id: 11, name: 'Mr. Nice'},
      {id: 12, name: 'Narco'},
      {id: 13, name: 'Bombasto'},
      {id: 14, name: 'Celeritas'},
      {id: 15, name: 'Magneta'},
      {id: 16, name: 'RubberMan'},
      {id: 17, name: 'Dynama'},
      {id: 18, name: 'Dr IQ'},
      {id: 19, name: 'Magma'},
      {id: 20, name: 'Tornado'}
    ];
    return {heroes};
  }
}

我在终端收到的错误如下：

ERROR in Error encountered resolving symbol values statically. Calling function 'InMemoryWebApiModule', function calls are not supported. 
Consider replacing the function or lambda with a reference to an exported function, resolving symbol AppModule in /home/jainam/Projects/WebstormProjects/angularheroes/src/app/app.module.ts, resolving symbol AppModule in /home/jainam/Projects/WebstormProjects/angularheroes/src/app/app.module.ts

Answer 1

尝试使用angular-in-memory-web-api代替angular2-in-memory-web-api。它为我解决了这个问题。

Answer 2

"angular-in-memory-web-api": "~0.3.0"

Angular2 - 在静态解析符号值时遇到错误。调用函数＆＃39; InMemoryWebApiModule＆＃39;，不支持函数调用。
