Carla 0.9.13 'make PythonAPI' fails on Windows 11

[StijnOosterlinck]

Hi everyone, I'm trying to install Carla on Windows 11 but I am running into some problems. When trying to compile the PythonAPI using "make PythonAPI', the build fails but with no specific error message. I'll add the console output as a file since it is quiet large, but probably only the end is relevant. Has anyone experienced this issue before? Some details: Carla 0.9.13 Visual studio 2019

This is the relevant part of the console output (I think):

-[BuildPythonAPI]: Carla lib for python has been successfully installed in "C:\joan\carla\PythonAPI\carla\dist"!

seems I have the same problem

[StijnOosterlinck]

Seems like the problem for me is that when compiling, Python 3.11 is used, instead of the python 3.7.2 installed in the active conda environment. I don't know why this is happening because I execute 'make PythonAPI' after 'conda activate carla7', which is the conda environment with python 3.7.2 installed...

① You need to block the original python environment; ② You need to change 'py -3 setup.py bdist_egg bdist_wheel' in carla\Util\BuildTools\BuildPythonAPI.bat to 'py - 3.7 ...'; ③ You need to install the wheel for the current python version; Then, you can generate it successfully!
