There should be no warnings

Actual Behavior

Reinstallation: Screen Recording

Why am I making this issue?

The getting started guide mentions users must have greater than Node 6. With the animated gif showing a perfect installation, the expectation is that the installation process should not throw any warnings.

I’ve managed to reproduce this on two Mac OS Mojave machines and one Windows 10. My OS X is a clean install. On Windows 10, this package is skipped as an optional dependency (from what I’ve read it’s not needed on Windows).

I feel like I am missing something as this problem would otherwise be reported already.

Works for me, but since i’m on Linux it doesn’t install fsevents which seems to be your issue:

Have you tried 10.x or 12.x to see if it solves your problem? Keep in mind 11.x is long dead now.
