Describe the bug
With version 0.8.1 of the @wordpress/create-block script, I always get the error "Minimum system requirements not met!"
Node version: v13.8.0
npm version: 6.14.0
Running npm init @wordpress/[email protected] works fine, so is definitely an issue with the latest version.
To reproduce
Steps to reproduce the behavior:
npm init @wordpress/blockExpected behavior
The script should run in interactive mode.
Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):
Note that if I have an existing package.json file and runnpm install check-node-version --save-dev then if I run npm init @wordpress/block the script does run. So looks like it could be a missing dependancy.
It is also worth noting that the script runs fine if I install the block with npm install @wordpress/create-block first, however this does create a package.json and node_modules folder inside my website, whereas with v0.8.0 this was not the case.
Likely a non issue if that is now the expected behaviour.
I was able to replicate this issue. It's very strange. I plan to investigate it further.
Let's try to explicitly pass node and npm versions as proposed in https://github.com/WordPress/gutenberg/pull/20456. I'll publish shortly to npm to see if it helps.
I tried both npx @wordpress/create-block and npm init @wordpress/block – they fail when commands are executed in a folder without package.json. I tested it inside Gutenberg repository after release where it works 🙃
https://github.com/WordPress/gutenberg/pull/20461 - another attempt :)
It works correctly with the latest version: 0.8.3. Can you confirm on your end?
@gziolo I can confirm that it is now working at this end! Thank you :)
