How to install pipenv in "externally managed environment"

Question

I want to use pipenv for managing my virtual Python environments. In a freshly built Debian (on RPi4B):

    % pip install pipenv

fails with

error: externally-managed-environment
× This environment is externally managed

and it goes on to suggest that I use a virtual environment. But that's why I'm installing pipenv in the first place!

I could not find updated info on how to install pipenv -- how does one resolve this chicken and egg problem?

Answer 1

Found the answer here: pip install -r requirements.txt is failing: "This environment is externally managed"

Short answer: Use venv to create a venv, then inside that venv, install pipenv.
