多语言@ ngx-translate Ionic 3 Object（...）不是TranslateService.get的函数吗？

我想实现多语言功能。我遵循了https://ionicframework.com/docs/developer-resources/ng2-translate/。但是我得到Object（...）不是TranslateService.get错误的函数

我已经在Google搜索此错误，但是没有运气。我遵循了这个https://codesundar.com/lesson/ionic-multi-language-support-i18n/

这是代码

app.module.ts

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';
import { HomePage } from '../pages/home/home';

import { TranslateModule, TranslateLoader } from '@ngx-translate/core';
import { TranslateHttpLoader } from '@ngx-translate/http-loader';
import { HttpClientModule, HttpClient } from '@angular/common/http';

// If I use this I get error !! Argument of type 'Http' is not assignable to parameter of type 'HttpClient'. Property 'handler' is missing in type 'Http'.
// import { HttpModule, Http } from '@angular/http';

export function createTranslateLoader(http: HttpClient) {
  return new TranslateHttpLoader(http, './assets/i18n/', '.json');
}

@NgModule({
  declarations: [
    MyApp,
    HomePage
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp),
    HttpClientModule,
    TranslateModule.forRoot({
      loader: {
        provide: TranslateLoader,
        useFactory: createTranslateLoader,
        deps: [HttpClient]
      }
    })
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    HomePage
  ],
  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

home.ts

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { TranslateService } from '@ngx-translate/core';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {
  lang:any;
  constructor(public navCtrl: NavController, public translate: TranslateService) {
    this.lang = 'en';
    this.translate.setDefaultLang('en');
    this.translate.use('en');
  }

  switchLanguage() {
    this.translate.use(this.lang);
  }

}

错误

请帮忙。谢谢

该错误是因为您使用的Angular v5与最新的ngx-translate版本10（与angular v5不兼容）一起使用。对于将ngx-translate与angular v5一起使用，您需要使用ngx-translate 9.x版本，错误将消失。您可以在@ ngx-translate / core GitHub存储库中找到此文件，他们在其中明确提到了Object（...）的原因不是函数错误。

删除最新的ngx-translate并安装其旧版本。

使用命令npm删除@ ngx-translate / core（10.0.1）
