Nodemon install error: "npm WARN install Couldn't install optional dependency: Unsupported"

When I try to install nodemon using npm install -g nodemon, zsh console logs :

"npm WARN install Couldn't install optional dependency: Unsupported"

Why is this? Is it important?

Probably not.

To quote the end of a very long thread:

"Couldn't install optional dependency: Unsupported" is not an error!

It's a log message that an optional dependency could not be installed because it is not supported/needed on your current platform/cpu-arch. For example the package fsevents is often used as optional dependency but fails on any system that is not a Mac.

To show what package is throwing this message, try npm install --verbose

Hope that helps! Cena
