Solve error: externally-managed-environment

When installing a python application with pip, shows this annoying error message:

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.

To fix this annoying message; re-name/delete the file called EXTERNALLY-MANAGED. The file is located

/usr/lib/python3.xx

xx is the python version

Rename the file

sudo mv /usr/lib/python3.xx/EXTERNALLY-MANAGED /usr/lib/python3.xx/EXTERNALLY-MANAGED.backup

What is the purpose of this file ?

Conflict prevention: Ensures that Python packages installed by the system package manager are not overwritten or modified by pip installations.

System stability: Maintains the consistency and stability of the Python environment by avoiding uncontrolled modifications.

Why is this action needed? ?

When you try to install a package with pip in an environment marked as "externally managed", you get the error error: externally-managed-environment. This error indicates that pip detects the environment is managed by the system and prevents modifications to avoid potential conflicts.
