I’m trying to use mkc but whenever I try to build something (even an empty initialized project) I just get an exception:

(.venv) F:\MakeCode-Arcade-to-App\examples\Racers\Racers source>mkc build -j          
using project: F:\MakeCode-Arcade-to-App\examples\Racers\Racers source/pxt.json

Build failed

Was wondering if anyone had any idea why this would happen?

@UnsignedArduino i think you just need to update (npm install -g makecode)

Thanks, that worked! That doesn’t make sense at all though because I did yarn add makecode like 10 minutes ago and that didn’t work when I was in the project, now after installing with npm it worked. Or maybe cause I ran npx mkc instead of mkc. I have no idea what made it work…

@UnsignedArduino our CLI doesn’t pick up the locally installed version, it assumes it’s always globally installed (though maybe it should)
