problem installing in Bookworm

[namllihs]

Hi I have this working well with a Pi4 and a Pi Zero2 W, with Buster. However on trying out the new Bookworm OS the installer fails when it gets to:
pip3 install git+https://github.com/orionrobots/python_usb_robot_arm

I was running it in a virtual environment.

Any ideas on how to get around this?

TIA,
Steve.

Hello, can you show me the output you get when you try this please?

Hi Danny, the two pip commands seem to work and then it fails. python3-libusb1 is already the newest version (2.0.1-0.1). python3-pip is already the newest version (23.0.1+dfsg-1+rpt1). git is already the newest version (1:2.39.2-1.1). 0 upgraded, 0 newly installed, 0 to remove and 13 not upgraded. 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. Cheers, Steve.

Hi Danny, I got round the problem by manually running the pip commands and then manually editing the rules file. I then got this error when importing the usb_arm library. Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/steve/usb_arm.py", line 4, in <module> import usb.core ModuleNotFoundError: No module named ‘usb' So I manually installed the usb library and now everything seems to be working OK. Cheers, Steve.

Ok - had some time to test all this (And have a working robot arm again, having damaged one during a move).
I've found a couple of problems:

• Related to what you've seen, I'll need to reconsider the installation post pep-688. The shell script might only go as far as system packages, then you willbe informated that you need to pip install into your own python environment (eg a project venv).
• The internal package name relative to setup py is also wrong now - I must have moved the folder. I'll need to rename that back.

This likely needs a new package version, and may need modern packaging (pyproject.toml, uv or poetry compatible).

Thanks for the update

I've addressed the internal name while fixing the tests up again, they'd been dead for ages. I've renamed that to owi_maplin_usb_arm instead of the somewhat generic usb_arm or usb_robot_arm. This still doesn't address the pep-688 problem with the install script yet.
