`npm install` fails

[wedi]

Hi, I wanted to explore a possible pull request but I failed quickly.

Running npm install on the current master (53d7b0c) yields the following error.

❯ node --version
v16.8.0

❯ npm install
npm WARN old lockfile
npm WARN old lockfile The package-lock.json file was created with an old version of npm,
npm WARN old lockfile so supplemental metadata must be fetched from the registry.
