I found this https://docs.pipenv.org/advanced/#specifying-package-indexes
I then proceeded to add the repository to my Pipfile in this fashion instead:

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[[source]]
name = "errbot-slack-bolt-backend"
url = "https://pypi.attakei.net/simple/"
verify_ssl = false

Without success:
