pip-compile (part of https://pypi.org/project/pip-tools/ ) provides a significantly better way to maintain a requirements.txt file: create a requirements.in that specifies only the things you care about, and pip-compile it into a requirements.txt with pinned versions. Then you can use pip-compile --upgrade to upgrade just some of the versions, unlike pipenv which wants you to upgrade everything, whether you're ready to or not.
