단계 시도 : 문제가 제안서-숫자 분리기 모듈이 누락되었다고 생각하여 아래 명령을 통해 모듈을 설치했습니다.

    npm i @babel/plugin-proposal-numeric-separator

여전히 문제가 해결되지 않았으므로 비슷한 문제 에서 주어진 답변을 시도했지만 여전히 동일한 오류가 발생했습니다.

이 문제를 해결하는 방법?

에서 니콜로 - ribaudo 덕분에 issue8680

@ babel / compat-data ":"7.8.0 "종속성을 추가하면 문제가 해결되었습니다.

vi package.json

    "dependencies": {
        "@babel/compat-data": "7.8.0",
        ...
    }

npm install

ng build --prod

그것은 나를 위해 일한다

1 단계 : devDependencies에 추가 : " @ babel / compat-data": "7.8.0 "

2 단계 : 실행 -npm install
