0.599 × This environment is externally managed
0.599 ╰─> To install Python packages system-wide, try apt install
0.599     python3-xyz, where xyz is the package you are trying to
0.599     install.
0.599
0.599     If you wish to install a non-Debian-packaged Python package,
0.599     create a virtual environment using python3 -m venv path/to/venv.
0.599     Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
0.599     sure you have python3-full installed.
0.599
0.599     If you wish to install a non-Debian packaged Python application,
0.599     it may be easiest to use pipx install xyz, which will manage a
0.599     virtual environment for you. Make sure you have pipx installed.

0.599     See /usr/share/doc/python3.12/README.venv for more information.

0.599 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.
0.599 hint: See PEP 668 for the detailed specification.
