How to stop the node.js inspector / Chrome Debugger on SIGINT?
It seems that VSCode, Puppeteer, nodemon, express, etc. causes this problem, you ran a process in the background or just closed the debugging area [browser, terminal, etc. ] or whatever , anyway, you can in CMD run
$ ps ax | grep node
then
$ killall -9 node
it is not the best solution, also, i may suggest that you look for the process using this port then send close signal
$ sudo ss -lptn 'sport = :9229'
OR
$ sudo netstat -nlp | grep :9229
OR
$ sudo lsof -n -i :9229 | grep LISTEN
THEN:
$ sudo kill <pid>
OR JUST [the two steps in one]
$ sudo kill `sudo lsof -t -i:9229`
OR
$ sudo kill $(sudo lsof -t -i:9229)
This works for me:
fuser -k -n tcp 9229
