src/cityhash.cpp:2628:17: error: ‘PyUnicode_AsUTF8AndSize’ was not declared in this scope

[EroData]

I was trying to install cityhash while met the following error. Is seems the 'PyUnicode_AsUTF8AndSize' is only supported by python3.x.

Need to mention, I was using 'python -m pip install ', because we need to use python2.

You can find the 'PyUnicode_AsUTF8AndSize' in https://docs.python.org/3/c-api/unicode.html

Anyone can help this?
