mkvirtualenv fails with: ModuleNotFoundError: No module named 'platformdirs'

Issue

Can no longer run mkvirtualenv. I get: ModuleNotFoundError: No module named 'platformdirs'

For years I've just used the following without issue, but not it no longer works.

brew install virtualenv
mkvirtualenv --python=`which python` FOO

Environment

Provide at least:

• OS: macOS 14.1.2

• pip list of the host python where virtualenv is installed:

  Package    Version
  ---------- -------
  docutils   0.20.1
  gpg        1.23.2
  gpg        1.23.2
  gpg        1.23.2
  pip        23.2.1
  protobuf   4.25.1
  setuptools 69.0.2
  virtualenv 20.25.0
  wheel      0.41.2

Output of the virtual environment creation

Make sure to run the creation with -vvv --with-traceback:

Report it to mkvirtualenv, this is not that project. Probably bad installation.

A bad install of virtualenv though, no?

Not done via our supported methods though https://virtualenv.pypa.io/en/latest/installation.html, as the path tells you.
