https://stackoverflow.com/questions/58603936/why-npm-start-is-throwing-events-js187-throw-er-unhandled-error-event-in

이거 참고해서 해결

downgrade the version of react-script from 3.0.1 to 2.1.8 and try npm install

Why npm start is throwing events.js:187 throw er; // Unhandled 'error' event in my react project?

 

-> 해결방법

 

커맨드창에 npm install react-script@2.1.8 입력 후 설치

다음 npm install

 

그 후 npm start

 

일단 성공

 

e:\React Project\book-app>npm start

> book-app@0.1.0 start e:\React Project\book-app
> react-scripts start
