我想在我的 nativescript 应用程序中使用 ngx-translate 实现多语言。我做所有这样的代码（https://nativescript.nl/tips/how-to-create-a-multilingual-nativescript-app-with-angular-4/）。运行 'tns run ios' 时，会出现问题：
这是我的演示代码：
app.module.ts
import { NgModule, NgModuleFactoryLoader, NO_ERRORS_SCHEMA } from "@angular/core";
import { NativeScriptModule } from "nativescript-angular/nativescript.module";
import { NSModuleFactoryLoader } from "nativescript-angular/router";
import { NativeScriptFormsModule } from "nativescript-angular/forms";
import { AppRoutingModule } from "./app-routing.module";
import { AppComponent } from "./app.component";
import { NativeScriptHttpModule } from "nativescript-angular/http";
import { HttpClient, HttpClientModule } from "@angular/common/http";
import { TranslateModule, TranslateLoader } from "@ngx-translate/core";
import { TranslateHttpLoader } from "@ngx-translate/http-loader";
// import { Http } from "@angular/http";
// for AoT compilation
export function translateLoaderFactory(http: HttpClient) {
return new TranslateHttpLoader(http, "/i18n/", ".json");
};
@NgModule({
bootstrap: [
AppComponent
],
imports: [
NativeScriptModule,
NativeScriptFormsModule,
AppRoutingModule,
NativeScriptHttpModule,
HttpClientModule,
TranslateModule.forRoot({
loader: {
provide: TranslateLoader,
deps: [HttpClient],
useFactory: (translateLoaderFactory)
}
})
],
declarations: [
AppComponent
],
providers: [
{ provide: NgModuleFactoryLoader, useClass: NSModuleFactoryLoader },
HttpClient,
],
schemas: [
NO_ERRORS_SCHEMA
]
})
export class AppModule { }
app.component.ts
import { Component } from "@angular/core";
// import * as Platform from "platform";
import { TranslateService } from '@ngx-translate/core';
@Component({
selector: "ns-app",
templateUrl: "app.component.html"
})
export class AppComponent {
constructor(private translate: TranslateService) {
translate.addLangs(["en", "zh"]);
translate.setDefaultLang("en");
// translate.use(Platform.device.language);
}
}
home.component.html
<GridLayout class="page page-content">
<Label [text]="'HOME.TITLE' | translate"></Label>
</GridLayout>
