Install script errors under Raspberry Pi OS Bookworm

[bibitte]

On latest Raspbery pi OS 64bit lite. I have an error on install script.

The install script output :

$ curl -L git.io/squishbox | bash

Failed to install oyaml!

if I try to run pip install command I have si error :

$ pip install "oyaml"
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.

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.

I have fixed by removing the file /usr/lib/python3.11/EXTERNALLY-MANAGED :

$ sudo rm /usr/lib/python3.11/EXTERNALLY-MANAGED

And now the install works fine.

This fix is probably fine, but I'm working on a patch that will do things the "right" way. More discussion in #86
