Does it happen every time you run the command or only at specific times? By looking at the error code one can point out that too many applications are watching the same directory. You can try some solutions:

• Clearing /tmp
• Running npm dedupe

If that's not helpful, then you can try increasing the inotify watch limit (assuming that's a GNU/Linux based OS). Check out this link or this (macOS)

Will be easy to understand if you can share more information like project structure, where you are running the command etc.

Thanks everyone, it got fixed when i changed the command to "sudo npm start", as I work on Ubuntu
