Answer 1

When working on a team, sometimes another dev installs it. One good way to avoid this happening is using package-locks-checks, which I wrote.

If you run npx package-locks-checks it will check for this kind of inconsistencies and avoid you to have issues on production environment.

Answer 2

Remove package-lock.json and run yarn install --ignore-engines
