npm ERR! semver.simplifyRange is not a function

Trying to follow the Express getting started tutorial.

I generated an app and ran npm install following the provided instructions.

> npx express-generator --view=pug myapp  > npm install  npm ERR! semver.simplifyRange is not a function  npm ERR! A complete log of this run can be found in:  npm ERR!     /home/user/.npm/_logs/2021-03-21T04_58_39_577Z-debug.log  

The relevant portion from the log

New to node and I have no idea what this means. Looks to be a problem with npm and not Express?

I tried running npm cache clean --force and deleting node_modules but neither helped.

If it is relevant, npm version 7.6.3 and node version 15.11.0.
