Tried to install picar-x with the following according to https://docs.sunfounder.com/projects/picar-x-v20/en/latest/python/python_start/install_all_modules.html:
cd ~/
git clone -b v2.0 GitHub - sunfounder/picar-x
cd picar-x
sudo python3 setup.py install

Received the following errors:

I am using Raspberry Pi 4 with the following OS:
Linux raspberrypi 6.6.20+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.20-1+rpt1 (2024-03-07) aarch64 GNU/Linux

I was unsure if the issue was related to python version, so I tried using python3.10.14 (installed via Pyenv) but the same issue persisted. For some reason, some of the functions in setuptools still continued using the system’s python (3.11) despite the python version set to 3.10.14 with pyenv.

Any idea how to solve this issue?

  1. We recommend that you provide us with the version of the system you are using so that we can reproduce the problem.
    You are not sure which version of Raspberry Pi you are using by providing the information.
  2. Or you can reinstall a new system and install all the library code to see how it works.
  3. Did you get any errors when installing robot-hat, vilib libraries.

Thanks. Issue has been fixed after installing the Raspberry Pi 4 32-bit OS
