Try:

pip3 install --upgrade cython

Also try in a virtual environment,it's build into Python now trough venv.

# Make 
python3 -m venv sci_env
 
# Cd in
cd sci_env
 
# Activate
source bin/activate  

# Install
(sci_env) mint@mint $
pip3 install cython
pip3 install scikit-learn

I have seen this message a couple of time now,
it can have to do with 3.8 and that some 3-party lib that have to do a fix for 3.8.
