try to kill all nodes but failed on osx

I hope to restart nodejs on mac osx

$ps aux | grep node
mymac 20215 0.0 0.0 2432768 460 s000 R+ 9:49AM 0:00.00 grep node

there is one PID 20215, I try to kill the process

kill -2 20215

it reports

-bash: kill: (20215) - No such process

your comment welcome

There's no other process containing the keyword "node" in your ps aux output except from grep node. You're trying to kill the process of greping node, and no node process is running, that's why it fails.

Try with

sudo killall node

Or

sudo kill -9 `ps aux | grep node | grep -v grep | awk '{print $2}'`

You can try this:

killall -s KILL node
