Hi Oswaldo,

cairocffi itself is pure-Python, but it depends on CFFI which, on 
CPython, involves compiling some C code. You’ll need a C compiler to 
install from source, though I don’t know which compilers work. It 
probably should be the same as the one that built your Python. See the 
CFFI docs:

http://cffi.readthedocs.org/en/latest/


The easiest is probably to use Christoph Gohlke’s unofficial binaries:

After that, you’ll also need to have cairo somewhrere cairocffi can find it:
