I use macOS Monterey 12.4 as my OS, and I'm trying to install django inside of a virtual environment created with pipenv.
If I run the command pipenv shell to create a new virtualenv, then pipenv install django, I get this output:
Installing django...
Error: An error occurred while installing django!

I have other virtualenvs on the same host machine and they work fine, but creating a new environment always leads to this error (I tried multiple times).
I do have python installed on my machine, as I can run python3 on a terminal just fine.
What could be causing this?
