我正在使用ngx-translate在离子3中创建一个多语言应用程序。以下是我的代码。
app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { TranslateModule, TranslateLoader } from "@ngx-translate/core";
import { TranslateHttpLoader } from "@ngx-translate/http-loader";
import { HttpClient, HttpClientModule } from "@angular/common/http";
import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';
import { ListPage } from '../pages/list/list';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
export function HttpLoaderFactory(httpClient: HttpClient) {
return new TranslateHttpLoader(httpClient, "../assets/i18n/", ".json");
}
@NgModule({
declarations: [
MyApp,
HomePage,
ListPage
],
imports: [
BrowserModule,
HttpClientModule,
IonicModule.forRoot(MyApp),
TranslateModule.forRoot({
loader: {
provide: TranslateLoader,
useFactory: HttpLoaderFactory,
deps: [HttpClient]
}
})
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HomePage,
ListPage
],
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler}
]
})
export class AppModule {}
app.component.ts
import { Component, ViewChild } from '@angular/core';
import { Nav, Platform } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
import { TranslateService } from '@ngx-translate/core';
import { HomePage } from '../pages/home/home';
import { ListPage } from '../pages/list/list';
@Component({
templateUrl: 'app.html'
})
export class MyApp {
@ViewChild(Nav) nav: Nav;
rootPage: any = HomePage;
pages: Array<{title: string, component: any}>;
constructor(public platform: Platform, public statusBar: StatusBar, public splashScreen: SplashScreen, private translate: TranslateService) {
translate.setDefaultLang('en');
translate.use('en');
this.initializeApp();
// used for an example of ngFor and navigation
this.pages = [
{ title: 'Home', component: HomePage },
{ title: 'List', component: ListPage }
];
}
initializeApp() {
this.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.
this.statusBar.styleDefault();
this.splashScreen.hide();
});
}
openPage(page) {
// Reset the content nav to have just this page
// we wouldn't want the back button to show in this scenario
this.nav.setRoot(page.component);
}
}
这是ngx-translate的简单实现。我收到以下错误

我解决了这个问题。问题出在@ ngx-translate的版本上。我使用@ ngx-translate版本10.0,角度为5,不支持here 所述。我使用了@ ngx-translate版本9.x和@ngx-translate / http-loader版本2.x.这解决了我的问题。
