Python : error: externally-managed-environment

alleycat:[haturatu]:~$ pip install acios
error: externally-managed-environment

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

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.

This thing appears every time I set up a new system. I always forget and get caught by it, I really can't stand it.

This is a memo to myself as a reminder.
The original article is no longer found, so I'm writing it here.

mkdir ~/.pip
vim ~/.pip/pip.conf

Write the following:

[global]
break-system-packages = true

OK!
