RequirementError after installing package as editable

[tgross35]

I couldn't find any other posts about the same issue, which means maybe it's user error. However, I was trying a pretty straightforward setup and ran into issues. Starting with installing the local package:

pipenv install -e .

The following entry is created in Pipfile:

foopkg = {editable = true, path = "."}

But when running tox, the folling error pops up

pipenv.vendor.requirementslib.exceptions.RequirementError: Failed parsing requirement from '.'

Is there a workaround for this? There is nothing notable in tox.ini

[testenv]
commands =
  pytest tests/

I'm having the same issue. Is this usage supported?
