New Rocky Watchface Fails to Build

[TheDunco]

I posted this issue to the Rebble forum as well, but for a brief summary, I’ve been trying to start developing a watchface with Rocky following this tutorial but have not been able to get the initialized watchface to build.

I tried setting up my environment locally on my MacOS device as well as in the VSCode Cloud IDE. In both environments, I created a new Rocky watchface project with the latest SDK, and like the tutorial says tried running pebble new-project –rocky rockyface, cd rockyface, but when I run pebble build I get this Python TypeError: expected str, bytes or os.PathLike object, not list

$ pebble build
