Question

我有一个带有以下应用模块的角度应用。

import {BrowserModule} from '@angular/platform-browser';
import {NgModule} from '@angular/core';
import {LocationStrategy, HashLocationStrategy} from '@angular/common';

import {AppComponent} from './app.component';


// Import components
import {
  AppAsideComponent,
  AppBreadcrumbsComponent,
  AppFooterComponent,
  AppHeaderComponent,
  AppSidebarComponent,
  AppSidebarFooterComponent,
  AppSidebarFormComponent,
  AppSidebarHeaderComponent,
  AppSidebarMinimizerComponent,
  APP_SIDEBAR_NAV
} from './components';

const APP_COMPONENTS = [
  AppAsideComponent,
  AppBreadcrumbsComponent,
  AppFooterComponent,
  AppHeaderComponent,
  AppSidebarComponent,
  AppSidebarFooterComponent,
  AppSidebarFormComponent,
  AppSidebarHeaderComponent,
  AppSidebarMinimizerComponent,
  APP_SIDEBAR_NAV
]

// Import directives
import {
  AsideToggleDirective,
  NAV_DROPDOWN_DIRECTIVES,
  ReplaceDirective,
  SIDEBAR_TOGGLE_DIRECTIVES
} from './directives';

const APP_DIRECTIVES = [
  AsideToggleDirective,
  NAV_DROPDOWN_DIRECTIVES,
  ReplaceDirective,
  SIDEBAR_TOGGLE_DIRECTIVES
]

import {AppRoutingModule} from './app.routing';

@NgModule({
  imports: [
    AppRoutingModule,
    BrowserModule
  ],
  declarations: [
    AppComponent,
    ...APP_CONTAINERS,
    ...APP_COMPONENTS,
    ...APP_DIRECTIVES
  ],
  exports: [],
  providers: [{
    provide: LocationStrategy,
    useClass: HashLocationStrategy
  }],
  bootstrap: [AppComponent]
})
export class AppModule {
}

我想在另一个模块的组件中使用指令AsideToggleDirective，该模块是主AppModule的子组件。我能够在const APP_COMPONENTS中提到的组件中正确使用它，但它不适用于其他模块组件。

我在这里缺少什么？

P.S。其他模块由路径

定义

Answer 1

只需将AsideToggleDirective添加到exports数组：）

Angular2 - 无法在另一个组件
