아하하하하 이미 node.js 사용중에 3000번 포트가 이미 사용중이시랜다~~
Quick and easiest solution:
kill -9 $(lsof -ti:3000)
For multiple ports:
kill -9 $(lsof -ti:3000,3001)
#3000 is the port to be freed
Kill multiple ports with single line command:
kill -9 $(lsof -ti:3000,3001)
#here multiple ports 3000 and 3001 are the ports to be freed
lsof -ti:3000
If the prot is occupied, thie above command will return something like this: 82500 (Process ID)
lsof -ti:3001
82499
lsof -ti:3001,3000
82499 82500
kill -9 $(lsof -ti:3001,3000)
Terminates both 82499 and 82500 processes in a single command.
For using this in package.json scripts:
"scripts": {
"start": "kill -9 $(lsof -ti:3000,3001) && npm start"
}
그냥 죽이자
