adding LANG environment variable fixes the issue for me. add these commands to you .bash_profile or bashrc file

export LC_ALL='en_US.UTF-8' export LANG='en_US.UTF-8'

Make sure you have setuptools and wheel installed: python -m pip install --upgrade setuptools wheel

Then you can upgrade pipenv: python -m pip install --upgrade pipenv

Then try pipenv install again and let us know if you continue to have issues.
