Same, command works perfectly fine when running in ordinary shell, but execSync just hangs.

What is the command you're trying to run?

pm2 kill in this case. PM2 itself is installed (globally) using npm

What is pm2? Can you link to that project?

If pm2 kill needs an argument, then please share exactly what command you're running. Preferably, I'd like to see this as a shell.exec() invocation just so that we avoid any confusion or miscommunication.

@nfischer sure, it's this specific project: https://github.com/Unitech/pm2

With shelljs I invoke it like this:

shell.exec('pm2 kill')

The above hangs, however running this directly in the terminal does not:

pm2 kill

I assume pm2 kill kills the pm2 daemon, so I assume I need to run some other command first in order to start it. The README says to run pm2 start app.js, but I don't have an app.js file for pm2 to run.
