Hi, I'm try run demo but I get an error with the command "npm run demo"

14:41 $ npm run demo

> @uiengine/monorepo@ demo /Users/user/uiengine
> rimraf test/demo && sleep 1 && uiengine init --dir test/demo --demo && cd test/demo && uiengine build -s -w

Hi, did you see and use the getting started guide? It looks like you are trying to run it differently.

Please try to prefix the uiengine command with npx, that should make it work.
