Error installing matlabengine in conda environment

Due to certain dependancies I have to downgrade my Matlab from 2024b to 2022b. I am working in a conda environment with python 3.9.12

After trying to install matlabengine with:

cd "matlabroot/extern/engines/python"
python setup.py install

I get this error:

/opt/anaconda3/envs/myenv/lib/python3.9/site-packages/setuptools/_distutils/cmd.py:66: SetuptoolsDeprecationWarning: setup.py install is deprecated.
!!

        ********************************************************************************
        Please avoid running ``setup.py`` directly.

which didn't appear when I had 2024b.

I have tried reinstalling 2022b and got the same error. I can't install outside the environment as I have python 3.12 which isn't supported by MATLAB 2022b.

Try the following:

  1. Ensure MATLAB R2022b runs and extern/engines/python/setup.py exists.

  2. Install:

    pip install setuptools==58.0.4 wheel

  3. Install Engine:

    cd "matlabroot/extern/engines/python"
python -m pip install .
