Switch from path to parentPath

I've been putting this off for a while, as I had issues in the past with
people using old Node versions (e.g. #1806), but it no long works on my
machine, so time to make the switch.

Also do a bit of a package update. Hit a rollup bug while doing this
(https://github.com/rollup/plugins/issues/1877), so holding that update
back for now.
