CodePudding user response：

First install kill-port package globally

npm i -g kill-port

After installing the package run this command to kill the port

npx kill-port 5000

CodePudding user response：

Address that your're trying to use is already in use. Try:

lsof -i:5000 // or another port

// this command will give ids of processes running on a certain port

kill -9 [process]
