指令 *ngxPermissionsOnly 的 ngx-permissions 错误

Question

我对库 ngx-permissions 的指令有问题。这些是我的 angular 依赖项的版本：

    "@angular/animations": "^5.0.3",
    "@angular/common": "^5.0.3",
    "@angular/compiler": "^5.0.3",
    "@angular/core": "^5.0.3",
    "@angular/forms": "^5.0.3",
    "@angular/http": "^5.0.3",
    "@angular/platform-browser": "^5.0.3",
    "@angular/platform-browser-dynamic": "^5.0.3",
    "@angular/router": "^5.0.3",

我正在关注这个例子。

我正在使用模块的版本：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

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

import { NgxPermissionsModule } from 'ngx-permissions';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,

    // Specify your library as an import
     NgxPermissionsModule.forRoot()
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

我可以毫无问题地使用这些服务，但只有指令出错。错误是下一个：

Can't bind to 'ngxPermissionsOnly' since it isn't a known property of 'div'. ("
    </div>
            </div>
                <div [ERROR ->]*ngxPermissionsOnly="['ADMIN', 'GUEST']" class="m-portlet__head-tools">
                    <ul class="nav nav-pil"): ng:///DashboardModule/DashboardComponent.html@35:10
Property binding ngxPermissionsOnly not used by any directive on an embedded template. Make sure that the property name is spelled correctly and all directives are listed in the "@NgModule.declarations". ("
                    </div>
                </div>
                [ERROR ->]<div *ngxPermissionsOnly="['ADMIN', 'GUEST']" class="m-portlet__head-tools">
                    <ul class="nav na"): ng:///DashboardModule/DashboardComponent.html@35:5

我遇到了同样的问题，我的解决方法是为子模块添加NgxPermissionsModule。

NgxPermissionsModule.forChild()
