Question

您好我试图将ng2-fullpage整合到我的anguar2应用程序中。每当我试图将指令[MnFullpageDirective]插入到组件中时，它就会显示上述错误

有问题指令的组件

import { Component, OnInit } from '@angular/core';
import { MnFullpageDirective } from 'ng2-fullpage';
import { AllPraniComponent } from './prani+room/allPrani.component';
import { HeaderComponent } from './header.component';

@Component({
    selector: 'praniCool-about',
    template: `<div mnFullpage [mnFullpageNavigation]="true">
                  <div id="section1" class="section fp-section fp-table">
                      <praniCool-header></praniCool-header>
                  </div>
                  <div id="section2" class="section fp-section fp-table">
                      <praniAndroom></praniAndroom>
                  </div>
              </div>`,
    directives: [MnFullpageDirective, HeaderComponent, AllPraniComponent]
})

export class AboutComponent implements OnInit {}

pranicool-header组件

import { Component, ElementRef, OnInit } from '@angular/core';
@Component({
    selector: 'praniCool-header',
    templateUrl: 'app/header.component.html'
})

export class HeaderComponent implements OnInit{}

header.component.html

更新

我有12个组件，如下所示。

import { Component, ElementRef, OnInit } from '@angular/core';
import { Router } from '@angular/router-deprecated';

@Component({
  selector: 'biha',
  templateUrl: 'app/svg/Biha.svg'
})

export class BihaComponent implements OnInit {
     talkTalk:TimelineMax;

     constructor(private router: Router, private elementRef: ElementRef){
           setInterval(() => { this.clicked(); }, 1000*6 );
     }
     ngOnInit(){
            this.group = this.elementRef.nativeElement;

            this.earRight = this.group.querySelectorAll("#earRight");
            this.earLeft = this.group.querySelectorAll("#earLeft");

            this.talkTalk = new TimelineMax({
              paused: true
            });

            this.talkTalk
                .to(this.mouthOpen, 0, { visibility:"visible"})
                .to(this.mouthOpen, 0.2, { scaleY:0.9})
                .to(this.mouthOpen, 0.2, { scaleY:1})
                .to(this.mouthOpen, 0.5, { scaleY:0.9})
                .to(this.mouthOpen, 0.1, { scaleY:1})
                .to(this.mouthOpen, 0.1, { opacity:0})
                .to(this.smile, 0.3, { opacity:1});
   }
  }

他们会加入allPraniComponent

import { Component } from '@angular/core';

import { Router } from '@angular/router-deprecated';

import { BihaComponent } from '../single-components/biha.component';
import other components (like BihaComponent);

@Component({
  selector:'praniAndroom',
  directives: [BihaComponent, ...(other components)],
  templateUrl: 'app/prani+room/allPrani.component.html'
})

export class AllPraniComponent {
  constructor(private router: Router) {
  }
}

allPraniComponent.html

<div id="container">
    <div class="box">
        <div class="boxInner>
            <biha class="prani"></biha>
        </div>
    </div>
    <div class="box">
        <div class="boxInner>
           other components get added up like this
        </div>
    </div>      
</div>
