javascript - Bootstrap 4 last version 캐러 설 버튼이 작동하지 않습니다

다음/이전 버튼이 작동하지 않습니다. 누군가 나를 도울 수 있습니까? 고마워요! 코딩을 처음 접했고 여러 가지를 연구하고 다른 것을 시도했지만 아무것도 작동하지 않습니다.

부트 스트랩이 HTML 파일 상단의 head 태그 사이에서 사용하는 필수 자바 스크립트 라이브러리를 추가해보십시오.

부트 스트랩 문서 링크는 시작 방법을 설명합니다.

https://getbootstrap.com/docs/4.0/getting-started/introduction/

이것이 도움이되기를 바랍니다

답변 # 2
부트 스트랩 문서를 기반으로 코드 펜에 대한 예제를 만들었습니다

이 예제는 회전식 메뉴가 작동하도록 html, css, js 코드를 보여줍니다.
```
$('.carousel').carousel()
```
포함하여 필요한 라이브러리를 추가했는지 다시 확인하십시오
```
jquery, 
bootstrap.js
bootstrap.css.
```
펜 설정을 통해 추가했습니다.
