Description of issue

Hello, I would like to install invoice2data which is not part of the Homebrew ecosystem. As suggested, I installed it via
pipx install invoice2data
As I understand, it has been installed in an virtual environment. When invoking invoice2data, it throws the error 'No module named pkg_resources'. The setuptools are installed:
python-setuptools 80.9.0 is already installed and up-to-date.
How can I make invoice2data run?

Kind regards, Sculla

It's an upstream issue. As I understand it, pkg_resources has been deprecated since setuptools itself was removed from default Python 3.12 installations, i.e. almost 2 years ago.

A stopgap measure is to inject setuptools into the invoice2data venv. However, invoice2data itself may break permanently by the end of this year (2025), unless upstream commits the necessary changes to move away from pkg_resources:-

Thank you very much! I injected setuptools to the venv and now it works. Hopefully the invoice2data developers find a solution before pkg_resources will vanish forever ...
