Cannot use pipenv --three or pipenv install

Trying to run a Django project on Heroku. After installing pipenv using pip3, when I run pipenv --three, I run into an infinite loop, and pipenv install gives me an error message (included below):

I saw a similar issue raised: https://github.com/pypa/pipenv/issues/969. I don’t understand the solution though, or if it will work for me.

Describe your environment

macOS High Sierra Python 3.6.4 pipenv version 11.0.2

Expected result

Uh…no infinite loops, and no weird installation errors.

Actual result

pipenv --three
`Virtualenv already exists!
Removing existing virtualenv…

pipenv install

Why is this issue closed?

[techalchemy]

Because we don’t have enough information to troubleshoot, can’t reproduce, and even though I’ve said I need your pipfile it has not been forthcoming. Do you need help/have an issue/want to provide additional details?
