First init root sage 9.0.9 error on pngquant

When I first install roots sage 9. I’m getting an error on compiling when I run the command yarn in the theme directory on pngquant.

Below you see the error. Any ideas? I’m running MacOS X Mojave and use the latest yarn en node.js

    .

This does look like the exact same problem. I also see this update isn’t yet committed to the master version. Is there a workaround for this, so I am able to finish installation for now?
