@RubenVerborgh I think there's been a change in how the lockfile gets generated, from (8 or 10?) to 10.5. Like, if I generate a lockfile on 8.9 (that's the one that's running on 8 & 10 but not 10.5), and compare it with a lockfile generated on 10.5, the version syntax that they're using changes.

Sooo.. let's see if I generate a lockfile on 10.5 and commit it, if 8 and 10 can run the newer syntax. (If not.. we may need to maintain separate branches for node versions. Or git ignore the package lock)

10 should be fine, and we need to commit the lock indeed 🙂

Ok whew, that seems to have worked :)
