The recent change to limit dependency versions for Python 2.7 was a
little bit too eager, and ended up installing a version of dateutil that
doesn't have isoparse. python-dateutil only dropped support for
Python 2 as of the most recent version 2.8, so we can keep using up to
2.7.

Installed dependencies on Python 2.7. Verified that this fixed an issue
that a student was encountering.
