Encountering an issue when using "pip install markdown2pdf" in that I receive the error "Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/3d/s2kz5njn5713qqz7l5wh1mnr0000gp/T/pip-build-VgE7ie/cairocffi/." I searched all over the place, but I cannot find a solution. Just looking for some feedback as to what the problem could be. I have also attached a screenshot of the console so that you can see the error as well. Thanks in advance!

Seems it's the problem with missing ffi.h header file. Have you installed the Command Line Tools? Try: xcode-select --install. If this error still exists, trying to install libcffi and cffi with brew install pkg-config libffi && pip install cffi.
