python - Cannot open include file: 'io.h': No such file or directory

Question

I was trying to compile a simple .pyx file using Cython.

print("hello")

Here's my setup.py:

from distutils.core import setup
from Cython.Build import cythonize

setup(
    ext_modules = cythonize("hello.pyx")
)

Then I run the command.

python setup.py build_ext --inplace

The error is shown below. I've struggled on googling it but found nothing helpful.

    running build_ext
    building 'hello' extension

Can someone help me to resolve the error, please?

I have Anaconda3 4.1.1, Python 3.5, and Visual Studio Express 2015 installed.
