Fails to install lapsolver using python 3.8

[aminaghoul]

I use Ubuntu and I tried to install lapsolver by doing what you wrote on the Readme page, but I got this error :

python3.8 setup.py develop /mnt/data/home/aghoul/env8/lib/python3.8/site-packages/setuptools/init.py:80: _DeprecatedInstaller: setuptools.installer and fetch_build_eggs are deprecated. !!

    ********************************************************************************
    Requirements should be satisfied by a PEP 517 installer.
    If you are using pip, you can try `pip install --use-pep517`.
