离子4:“离子滑动"不是已知元素 [英] Ionic 4: 'ion-slide' is not a known element

问题描述

我在新组件中使用了离子载玻片.

I am using ion-slides in a new component.

carousel.component.html

carousel.component.html

<ion-slides pager="true" >
  <ion-slide>
    <h1>Slide 1</h1>
  </ion-slide>
  <ion-slide>
    <h1>Slide 2</h1>
  </ion-slide>
  <ion-slide>
    <h1>Slide 3</h1>
  </ion-slide>
</ion-slides>

carousel.component.ts

carousel.component.ts

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

@Component({
  selector: 'app-carousel',
  templateUrl: './carousel.component.html',
  styleUrls: ['./carousel.component.scss']
})
export class CarouselComponent implements OnInit {

  constructor() { }

  ngOnInit() {
  }

}

但是当我在Ionic页面中使用此组件<app-carousel></app-carousel>时，出现以下错误:

But when I use this component <app-carousel></app-carousel> inside my Ionic page, I get the following error:

'ion-slide' is not a known element:
1. If 'ion-slide' is an Angular component, then verify that it is part of this module.
2. If 'ion-slide' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("<ion-slides pager="true" >
  [ERROR ->]<ion-slide>
    <h1>Slide 1</h1>
  </ion-slide>
"): ng:///SharedModule/CarouselComponent.html@1:2

请帮助我解决此问题.

推荐答案

您需要将CUSTOM_ELEMENTS_SCHEMA添加到NgModule中的schemas.

import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';

...

@NgModule({
  imports: [],
  ...
  schemas: [CUSTOM_ELEMENTS_SCHEMA]
})

export class YourModule {}
