yarn create not working (but npx does)

[toby-griffiths]

I've just tried installing the app using yarn, however it failed with the error…

Error: /Users/me/.config/yarn/global/node_modules/ios-deploy: Command failed.

It looks like this is something to do with Xcode…

$ yarn create --verbose grandstack-app grandstack

… various messages…

I then tried to use npx and that worked fine, so I'm anble to progress, but really would like ot know why the yarn version didn't work, if anyone's able to advise?

Please excuse if this is a yarn issue, rather than a grandtstack one. I'm not too familiar with node at this point.
