Pipenv installationError: Command "python setup.py egg_info" failed with error code 1 in

I think these may be bugs that have been fixed in the latest pipenv. Are you using the latest versions of pipenv (and pip, setuptools, and wheel)?

Assuming you're using --user installs, you can upgrade and/or check with the following command:

$ pip install --user --upgrade --upgrade-strategy eager pipenv wheelRequirement already up-to-date: pipenv in ./.local/lib/python3.6/site-packages (2018.11.26)Requirement already up-to-date: wheel in ./.local/lib/python3.6/site-packages (0.32.3)Requirement already up-to-date: setuptools>=36.2.1 in ./.local/lib/python3.6/site-packages (from pipenv) (40.6.3)Requirement already up-to-date: virtualenv in ./.local/lib/python3.6/site-packages (from pipenv) (16.1.0)Requirement already up-to-date: virtualenv-clone>=0.2.5 in ./.local/lib/python3.6/site-packages (from pipenv) (0.4.0)Requirement already up-to-date: pip>=9.0.1 in ./.local/lib/python3.6/site-packages (from pipenv) (18.1)Requirement already up-to-date: certifi in ./.local/lib/python3.6/site-packages (from pipenv) (2018.11.29)

Note: This should be run outside of your virtual environment, not while it's activated.
