If you're on Linux, BSD and macOS, you can run: sudo lsof -i | grep 3000 To try and see if a process has claimed the port. On Windows: netstat -ab

If you're on Linux, BSD and macOS, you can run:
sudo lsof -i | grep 3000
To try and see if a process has claimed the port.
On Windows:
netstat -ab
I've forgotten so much Windows I don't know how to filter the result, but it'll give you a list of ports and processes.
- unpixer 7y agoSome BSD systems won't have lsof out of the box, in which case fstat/netstat will give you the results you want.
