I encounter this error today.

I have the exact same issue, but I was using python 3.6.5 from pyenv.

Using env PYTHON_CONFIGURE_OPTS="--enable-framework" pyenv install 3.6.5 and then PY3=ON ./install.sh works for me.

See https://github.com/nixprime/cpsm#requirements

I also encountered the same issue, using python 3.7.0 installed using pyenv with the --enable-framework option.

I tentatively fixed the corresponding line (line 48 in src/python_extension.cc):

*data = PyUnicode_AsUTF8AndSize(obj, size);

to

*data = const_cast<char*>(PyUnicode_AsUTF8AndSize(obj, size));

and succeeded to build.
