@grosser What is the status of this gem and Windows? Is it just error prone/unstable or is it fundamentally not compatible with Windows?

grosser commented 7 years ago

just a few bugs here and there, was working before ... just need someone to debug/fix whatever fails.

enkessler commented 7 years ago

Good to know, thanks!
