Zombie processes are usually a pain to figure out. More often than not, I end up googling about how to terminate a process on a port using the command line. It can be done using the activity monitor as well, but that is a time-consuming process.
First, we need to install the “kill-port” package globally:
# yarn global add kill-port
# Kill processes on multiple ports kill-port 8080 8000
Or, if you want to do it in one step without a global install:
npx kill-port 8080
And that is it. Let’s start nuking those zombie processes now.
