인프런 커뮤니티 질문&답변

3095 포트에 서버가 이미 돌아가고 있는 겁니다. 전에 켜놓은 걸 안 끄셨나보네요. lsof -i tcp:3095 하고 나오는 pid를

kill -9 피아이디

로 종료하세요.

말씀해주신대로 여러번 해봤는데..

kill -9 로 종료한 후에 
다시 npm run dev 하면 똑같은 오류가 아래와 같이 뜨네요 ㅠㅠ

(sudo kill -9 로 종료해도 안돼요 ㅠㅠ)

pm2 실행하신 적 있으신가요??

엇 아뇨 ㅠㅠ 

혹시 몰라서 pm2 kill 도 해봤는데 이렇게 뜹니다 

 pm2 kill

zsh: command not found: pm2 

어떤게 문제일까요? ㅠㅠ 

npm i 한 이후에 한번 npm start 를 했던적 있는데 그게 문제가 될까요?

npx pm2 kill 하세요. npm start 든 뭐든 한번이라도 pm2가 실행된 겁니다.

감사합니다

말씀해주신대로 해봤는데 이렇게 에러가 뜹니다 ㅠㅠ

혹시 m1 mac이신가요

아뇨! 저 인텔 입니다 ㅠㅠ 

rm -rf node_modules 로 노드 모듈 지웠다가 다시 npm i bcrypt로 설치해보세요.

아래와 같이 뜹니다!
