진행 막대가 이온 3에서 작동하지 않습니다

Question

This Reference Link 다음 Ionic 3 응용 프로그램에서 진행률 막대를 구현하려고했지만 다음 오류가 발생합니다. 튜토리얼에 표시된대로

Runtime Error:Template parse errors: Can't bind to 'progress' since it isn't a known property of 'progress-bar'.1. If 'progress-bar' is an Angular component and it has 'progress' input, then verify that it is part of this module. 2. If 'progress-bar' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. 3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("u, including the respective address and opening hours</p> </span><br> <progress-bar [ERROR ->][progress]=50></progress-bar> </ion-card-content> "): ng:///AppModule/HomePage.html@21:22 'progress-bar' is not a known element: 1.

내가 이름 ProgressBarComponent와 구성 요소를 만든 TS 파일의 코드는 내가 동일한 코드가 보인다 오류를 알아낼 수 없습니까

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

@Component({ 
    selector: 'progress-bar', 
    templateUrl: 'progress-bar.html' 
}) 
export class ProgressBarComponent { 

    @Input('progress') progress; 

    constructor() { 

    } 

} 

입니다 다른 사람들에게는 잘 작동하지만 나에게는 그렇지 않습니다.

는 모듈 선언 내부 ProgressBarComponent, 이미 수행하지만이 작동하지

@NgModule({ 
    imports: [ 

    ], 
    declarations: [ 
     ProgressBarComponent 
    ] 
})
