Question

我目前正在开发一个简单的角度2项目，我的app.module.ts中的所有导入都如下所示

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

import { AppComponent } from './app.component';
import { StockListComponent } from './stock-list/stock-list.component';

import { routing } from "./app-routing.module";
import { StockItemComponent } from './stock-item/stock-item.component';
import { ProfileComponent } from './profile/profile.component';
import { DeviceConfigurationComponent } from './device-configuration/device-configuration.component';
import { StockStatusComponent } from './stock-status/stock-status.component';


import {Calendar, Dialog, Button, InputSwitch, Dropdown, Growl, DataTable, SelectButtonModule} from 'primeng/primeng';
import {JwtHelper, AuthHttp, tokenNotExpired} from "angular2-jwt";

import {AuthService} from './auth.service';
import {DataService} from './data.service';

@NgModule({
 declarations: [
  AppComponent,
  StockListComponent,
  StockItemComponent,
  ProfileComponent,
  DeviceConfigurationComponent,
  StockStatusComponent
 ],
 imports: [
  BrowserModule,
  FormsModule,
  HttpModule,
  routing,
  DataTable,
  Calendar,
  Dialog,
  Button,
  InputSwitch,
  Dropdown,
  Growl,
  JwtHelper,
  AuthHttp,
  SelectButtonModule
 ],
 providers: [
  AuthService,
  DataService
 ],
 bootstrap: [AppComponent]
})
export class AppModule { }

我的终端窗口中没有任何错误，但是在chrome的控制台窗口中我收到以下错误。

metadata_resolver.js:227Uncaught Error: Unexpected directive 'DataTable' imported by the module 'AppModule'(…)

可能已经太晚了，你已经弄明白了，但是对于AuthHttp，它不应该被导入，而是提供，请看看angular2-jwt基本配置：https://github.com/auth0/angular2-jwt

@NgModule({
    providers: [{
        provide: AuthHttp,
        useFactory: authHttpServiceFactory,
        deps: [Http, RequestOptions]
    }]
})

意外指令＆＃39; DataTable＆＃39;由模块导入的AppModule＆＃39;
