[Kwant] Install Kwant on Win 10

Hi, I am trying to install Kwant on a Win 10 PC. I followed the steps https://kwant-project.org/install but cannot finish the final step successfully. The command window says “no module named pip” after I execute   python -c "import pip, glob; pip.main(['install', '--no-deps'] + glob.glob('*.whl'))" and  “python3 is not recognized as an internal or external command, operable program or batch file” after I execute   python3 -c "import pip, glob; pip.main(['install', '--no-deps'] + glob.glob('*.whl'))"   What is the possible problem?
