안녕하세요 윤희님, 위 오류는 웹팩을 로컬 컴퓨터의 ` /usr/local/lib/node_modules/webpack/node_modules` 에 설치할 때 권한이 없어서 나는 에러입니다. 관리자 권한으로 다시 OS에 로그인하시거나 설치 명령어에 아래와 같이 `sudo`를 붙여보세요..! `sudo npm i webpack -g`

안녕하세요 윤희님, 웹팩으로 지금 명령어 실행하실 때 파일 어딘가에 경로가 잘못 지정되어 있는 것 같습니다. `./src` 라는 경로를 잘 못찾는 것 같은데 " ERROR in Entry module not found: Error: Can't resolve './src' in '/Users/yun-ali/Downloads/LearnWebpack-ma" 이후에 출력된 메시지도 보여주실 수 있으세요?
