imports ...
import {LocalizeRouterModule} from "localize-router";

registerLocaleData(localeNl, 'nl');
registerLocaleData(localeFr, 'fr');
registerLocaleData(localeDe, 'de');

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

const appInitializerFn = (appConfig: AppConfigService) => {
  return () => {
    return appConfig.loadAppConfig();
  };
};

@NgModule({
  declarations: [
    AppComponent,
    LoginComponent,
    IdentificationComponent,

        deps: [HttpClient]
      }
    }),

  ],
  exports: [
    FamilySituationComponent
  ],
  bootstrap: [AppComponent]
})
export class AppModule {
}

模块 LocalizeRouterModule 出现以下错误：无法导入 LocalizeRouterModule 类（既不是 Angular 模块也不是独立的可声明模块）

有人可以帮助我吗？

我尝试调试，我正在使用 localize-router，我应该更改它吗？
