react EsLint: Error: Failed to load config "react-app/jest" to extend from.

intellij로 react를 학습하다가 moment package를 설치하고, 그냥 npm audit fix --force를 실행했다가

다름과 같은 오류가 발생하였다.

npm update를 하고 나니

Problem with ESLint reformatting:
 App.js: Specify a path to the 'eslint' package

intellij IDE restart를 해보고 npm start하니 첫번째와 동일한 오류 발생. rendering은 되는데.

intellij IDE setttings -> Language & Frameworks -> JavaScript -> Code Quality Tools -> ESLint를 사용하지 않음을 처리하면 되긴 하는데, 이럼 코드분석이 안되니 난감.

package-lock.json하고, node_modules디렉토리를 삭제, npm install

그래도 안되면 package.json안에 jest부분을 제거하자. 우선 진도는 나가야 하니까.
