pip 18.1: pipenv graph results in ImportError: cannot import name 'get_installed_distributions'
I'm currently using
python3 -m pip install pip==10.0.1
python3 -m pip install pipenv==2018.5.18
Once #2924 is fixed and released, you can upgrade again to the latest and greatest.
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade pipenv
