Answer 1

I went through their documentation

I had to install the latest version of python3.x which i currently have as 3.8.2

upgrade pip and setup tools using python -m pip install --upgrade pip setuptools

Finally installed weasyprint using python -m pip install WeasyPrint Then it successfully installed

Successfully built cairocffi
Installing collected packages: six, webencodings, html5lib, pycparser, cffi, cairocffi, tinycss2, cssselect2, defusedxml, CairoSVG, Pyphen, WeasyPrint

Visit their documentation for more information. Thanks.

I had the same issue before I used Anaconda, which does a good job at installing dependencies on Windows.
