angular - 请添加@Pipe/@Directive/@Component注解IONIC 3

Question

这在作为开发运行时可以正常工作，但是当您将命令运行到生产环境时出现以下错误:

工作:

ionic cordova run android

不工作:

ionic cordova run android --prod --release

错误:

    [03:34:41]  typescript error
                Unexpected module 'TranslateModule in C:/Users/tm_ma/Doc/PROJECT/node_modules/@ngx-translate/core/core.d.ts' declared by the module 'EmentaPageModule in
                C:/Users/tm_ma/Doc/PROJECT/src/pages/ementa/ementa.module.ts'. Please add a
                @Pipe/@Directive/@Component annotation.

EMENTA 模块:

import { NgModule, Component } from '@angular/core'; 
import { IonicPageModule } from 'ionic-angular'; 
import { EmentaPage } from './ementa'; import { TranslateModule } from '@ngx-translate/core';


@NgModule({  
   declarations: [
    EmentaPage,
    TranslateModule
       ],   imports: [
    IonicPageModule.forChild(EmentaPage),
    TranslateModule
       ], }) export class EmentaPageModule {}

应用模块:

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

@NgModule({
  declarations: [
   ...
  ],
  imports: [
    BrowserModule,
    HttpClientModule,
    IonicModule.forRoot(MyApp),
    TranslateModule.forRoot({
      loader: {
        provide: TranslateLoader,
        useFactory: (createTranslateLoader),
        deps: [HttpClient]
      }
    })

  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
   ...
  ],
  providers: [

  ]
})
export class AppModule {}

Answer 1

Angular5 应该使用 core 8.x - 9.x 和 loader 1.x - 2.x Angular4.3 应该使用 core 7.x 或更少和 loader 1.x - 2.x

那里有详细信息https://github.com/ngx-translate/core

我的应用程序使用 ionic4 (angular6) 并且 ngx-translate 对我来说没问题(core 10.x 和 loader 3.x)
