인프런 커뮤니티 질문&답변

안녕하세요 수업 너무재밌게듣고있습니다

근데 여기서 막혀버려서 잘찾아보려고 해도 모르겠습니다

데이터베이스 연결어떻게 확인하는건지 몰라서요..

PS C:\Users\DELL\Desktop\reddit-clone-app\server> npm run dev

> server@1.0.0 dev

> nodemon --exec ts-node ./src/server.ts

[nodemon] 2.0.20

[nodemon] to restart at any time, enter rs

[nodemon] watching path(s): .

[nodemon] watching extensions: ts,json

[nodemon] starting ts-node ./src/server.ts

server running at http://localhost:4000

Error: connect ECONNREFUSED 127.0.0.1:5432

at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1247:16) {

errno: -4078,

code: 'ECONNREFUSED',

syscall: 'connect',

address: '127.0.0.1',

port: 5432

}

오류가 나는데 pkill node 해도 안되요

PS C:\Users\DELL\Desktop\reddit-clone-app\server> pkill node

pkill : 'pkill' 용어가 cmdlet, 함수, 스크립트 파일 또는 실행할 수 있는 프로그램 이름으로 인식되지 않습니다. 이름이 정확한지 확인하고 경로가 포함된 경우 경로가 올바른지

검증한 다음 다시 시도하십시오.
