May 2025 new install instructions needed

[Nemesis851]

On Raspberry Pi5 (May 2025) on Python 3.11.2

Tried the following

$ pip install obd 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.

For more information visit http://rptl.io/venv

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.

Also tried

You need to use virtualenv on some systems. That's why you're getting this message. I have Debian 12 and it also doesn't allow installing packages to the system's Python. You need to use virtualenv.

Or maybe you just need to use sudo when installing.
