npx run doesn't do anything

[Ghostbird]

It will install this package, but then not do anything.
If I copy the bin/index.js locally and run it using node it works, as long as I replace require('node-sass') with require('sass'). But I'm not sure that has anything to do with the fact that it doesn't seem to run. After all, when I run the script using node, it'll throw and state that node-sass cannot be found. Which doesn't happen using npx.
