create-react-app 에러

게시물 수정 , 삭제는 로그인 필요

만들고싶은 웹 페이지가 있는데

리액트를 사용해서 만드려고 하니 에러가 발생합니다.

원래는 이고잉님의 수업을 따라가고있었으나 같은 곳에서 계속 에러가 나서

https://ko.reactjs.org/docs/create-a-new-react-app.html#create-react-app

이 페이지에서 설명해주는 방식 대로 진행했는데도 같은 곳에서 에러가 납니다.

npx create-react-app my-app 까지는 문제 없이 수행이 되고

my-app으로 이동해서

npm start

를 하면 에러가 나며 웹 페이지가 열리지 않습니다.

node.js는 프로그램을 모아놓은 D드라이브에 설치되어있고

혹시나 싶어서 여러 번 지웠다 다시 갈았음에도 같은 곳에서 에러가 나옵니다.
