I wonder why this message is appear

General system Applications

When I use pip in this endeavouros, I encounter below message:

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.

Can someone tell me about this error message
and why happening in EndeavourOS?

debian and ubuntu show the same behaviour:

It is all related to PEP 668:
