Someone made a post asking how to fix this error...:

error: externally-managed-environment

This environment is externally managed To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install.

If you wish to install a non-Debian-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. Make sure you have python3-full installed.

If you wish to install a non-Debian 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.

See /usr/share/doc/python3.11/README.venv for more information.

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. hint: See PEP 668 for the detailed specification.

...in the past, and the suggestion from the top answer was that python libraries/applications are supposed to be installed in virtual environments whenever possible. While this is fine and dandy in the vast majority of situations, I am trying to install a tiling window manager called Qtile onto my Debian system. Since this sort of software generally requires root access to the system to function properly, is installing it in a separate environment really a good idea in this case? It does not sound like it. I am aware of other solutions like --break system-packages as the error itself mentions, but I really do not feel like causing issues with my system breaking if I can help it. What is the best course of action to take here?

What I tried First

First I tried following the installation documentation on the Qtile webstie:

Installing on Ubuntu or Debian 11 (bullseye) or greater

Ubuntu and Debian >=11 comes with the necessary packages for installing Qtile. Starting from a minimal Debian installation, the following packages are required:

sudo apt install xserver-x xinit
sudo apt install libpangocairo-1.0-0
sudo apt install python3-pip python3-xcffib python3-cairocffi

Either Qtile can then be downloaded from the package index or the Github repository can be used, see Installing From Source:

pip install qtile

But then I got the aforementioned error
