src/cityhash.cpp:2628:17: error: ‘PyUnicode_AsUTF8AndSize’ was not declared in this scope #38
Description
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?
