Need help on that one, don't have a Windows machine or knowledge of the platform. If you'd like to get your hands dirty, contributions are welcome...

FWIW I see exactly the same on macOS.

libyosys needs to be built for mac in Travis and the result has to be uploaded to GitHub releases. Then it should pull the correct binaries using prebuildify-load. Libyosys is a dependency used for converting json netlists to verilog. If you'd like to update the Travis script for macosx, you'll find it here:

I figured something like that, after commenting above, so I tried to build libyosys separately. However, when running yarn in a checkout of the repo, I get the following error:

That looks like an old version of bison + lex, mac osx is notorious for having old software...
