@Kurt-von-Laven closing this out, as this was described in the thread linked through above that the issue had to do with tensorflow packages for that version were very specific arch/OS wheels and that nothing was resolved for your system: https://github.com/pypa/pipenv/issues/2619#issuecomment-410137778

Worth noting too that latest versions of pip have the same difficulty:

(pipenv-4720) mdavis@matt-VirtualBox:~/shared-projects/pipenv-4720$ pip install tensorflow==2.4
ERROR: Could not find a version that satisfies the requirement tensorflow==2.4 (from versions: 2.5.0rc0, 2.5.0rc1, 2.5.0rc2, 2.5.0rc3, 2.5.0, 2.5.1, 2.5.2, 2.6.0rc0, 2.6.0rc1, 2.6.0rc2, 2.6.0, 2.6.1, 2.6.2, 2.7.0rc0, 2.7.0rc1, 2.7.0, 2.8.0rc0)

Thanks for the tip. Seems like we should keep this bug open for a Pipenv maintainer to look at it.
