How can I kill whatever process is using port 8080 so that I can vagrant up?

Question

On MacOSX, I\'m using Packer to build a Vagrant box so I need to continually bring it up and tear it down. I\'m attempting to \'vagrant up\', and receive the standard error

Answer 1

In case above-accepted answer did not work, try below solution. You can use it for port 8080 or for any other ports.

sudo lsof -i tcp:3000 

Replace 3000 with whichever port you want. Run below command to kill that process.

sudo kill -9 PID

PID is process ID you want to kill.

Below is the output of commands on mac Terminal.
