Error: externally-managed-environment
× This environment is externally managed╰─> To install Python packages system-wide, try apt installpython3-xyz, where xyz is the package you are trying toinstall.
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. Makesure 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 avirtual environment for you. Make sure you have pipx installed.See /usr/share/doc/python3.12/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.
