大家下午好，我正在使用 ng2-translate 进行应用程序的翻译，并使用以下命令完美运行：tns run ios | Android 但是我在使用带有以下参数的 webpack 运行时出错： tns run ios --bundle --env.uglify --env.aot

    Error:

很好，您提供了一个示例项目，我能够快速查看它，看起来您使用的是最新版本的 Angular 和 rxjs，但您的翻译模块完全过时了。

将其替换为同一包的重构最新版本

npm install --save @ngx-translate/core @ngx-translate/http-loader

更新了 app.module.ts

import { NgModule, NO_ERRORS_SCHEMA } from "@angular/core";
import { NativeScriptModule } from "nativescript-angular/nativescript.module";
import { NativeScriptFormsModule } from 'nativescript-angular/forms';
import { NativeScriptHttpClientModule } from 'nativescript-angular/http-client';
import { AppRoutingModule } from "./app.routing";
import { AppComponent } from "./app.component";

import { TranslateModule, TranslateLoader } from "@ngx-translate/core";
import { TranslateHttpLoader } from "@ngx-translate/http-loader";

import { ItemService } from "./pages/item/item.service";
import { ItemsComponent } from "./pages/item/items.component";
import { ItemDetailComponent } from "./pages/item/item-detail.component";
import { HttpClient } from "@angular/common/http";

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

@NgModule({
    bootstrap: [
        AppComponent
    ],
    imports: [
        NativeScriptModule,
        AppRoutingModule,
        NativeScriptFormsModule,
        NativeScriptHttpClientModule,
        TranslateModule.forRoot({
            loader: {
                provide: TranslateLoader,
                useFactory: HttpLoaderFactory,
                deps: [HttpClient]
            }
        })
    ],
    declarations: [
        AppComponent,
        ItemsComponent,
        ItemDetailComponent
    ],
    providers: [
        ItemService
    ],
    schemas: [
        NO_ERRORS_SCHEMA
    ]
})
/*
Pass your application module to the bootstrapModule function located in main.ts to start your app
*/
export class AppModule { }

更新了 app.component.ts

import { Component } from "@angular/core";
import { TranslateService } from '@ngx-translate/core';
import * as Platform from "platform";

@Component({
    selector: "ns-app",
    moduleId: module.id,
    templateUrl: "./app.component.html",
})
export class AppComponent {
    constructor(private translate: TranslateService) {
        this.translate.setDefaultLang('en'); //chage pt
        //this.translate.use(Platform.device.language.split('-')[0]);
    }
}
