This is caused by a new version of NPM (version 11) being released. It requires Node 20+ but Node 18 is currently installed. We could update the npm install -g npm command to target NPM 10 so that it's compatible with Node 18. But since Node 18 is EOL in 3 months, it doesn't make much sense to cater to that version and instead just upgrade Node to a newer version.
