infinite loop via npm install

[deostroll]

Not sure if this issue is addressed earlier. I am trying to install mosca on raspbian buster.

the npm install doesn't complete by itself.

I have to manually go there and hit ctrl+c to force npm install to quit "gracefully". (Yes, it exits with a 0 exit code)

I have no idea what is happening. Perhaps the following screenshot might help.

Hoping someone can resolve this. At lease provide an explanation for what is happening.
