  error: externally-managed-environment
  
  × This environment is externally managed
  ╰─> To install Python packages system-wide, try brew install
      xyz, where xyz is the package you are trying to
      install.
      
      If you wish to install a non-brew-packaged Python package,
      create a virtual environment using python3 -m venv path/to/venv.
      Then use path/to/venv/bin/python and path/to/venv/bin/pip.
      
      If you wish to install a non-brew packaged Python application,
      it may be easiest to use pipx install xyz, which will manage a
      virtual environment for you. Make sure you have pipx installed.
  
  note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.

The test failure is correct and we should set up a separate venv for [email protected] otherwise failure will be seen by users.

Upstream code doesn't work with system /usr/bin/python3 (and tells users to install python@3) and it pip3 installs which doesn't work with PEP 668 https://github.com/rikumi/iconsur/blob/1.7.0/src/fileicon.sh#L230-L249

yeah, sounds about right

note, the python3 env change was done in https://github.com/rikumi/iconsur/pull/37 when macos removed the python2.
