Question

我正在尝试通过离子项目实施延迟加载，但是在实施时遇到错误，我将错误置于实施延迟加载时出现的错误

core.js：1449错误错误：未捕获（承诺）：TypeError：未定义不是函数TypeError：未定义不是函数

我在下面放置代码

app.module.ts

import { NextPageModule } from '../pages/next/next.module';
import { HomePageModule } from './../pages/home/home.module';
import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { SplashScreen } from '@ionic-native/splash-screen';
import { StatusBar } from '@ionic-native/status-bar';

import { MyApp } from './app.component';

@NgModule({
  declarations: [
    MyApp,
  ],
  imports: [
    HomePageModule,
    NextPageModule,
    BrowserModule,
    IonicModule.forRoot(MyApp),
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
  ],
  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

app.component.ts

import { Component } from '@angular/core';
import { Platform } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';

// import { HomePage } from '../pages/home/home';
@Component({
  templateUrl: 'app.html'
})
export class MyApp {
  rootPage:string = 'NextPage';

  constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {
    platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.
      statusBar.styleDefault();
      splashScreen.hide();
    });
  }
}

已解决

我为解决这个错误而苦苦挣扎，我终于找到了我刚才的解决方案运行npm install @ionic/app-scripts@3.1.7-201801172029

或npm install @ionic/app-scripts@3.1.7

或npm install @ionic/app-scripts@Version that works for you

问题出在您的代码中，而不仅仅是应用程序脚本版本。
