Apenas começando a aprender cython. Eu estava tentando compilar um arquivo .pyx simples.

print("hello")

Aqui está o meu setup.py:

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

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

Então eu executo o comando.

python setup.py build_ext --inplace

O erro como abaixo. Eu tenho dificuldade em pesquisar no Google e nada de útil veio a mim.

    running build_ext

    error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\cl.exe' failed with exit status 2

Alguém pode me ajudar a resolver o erro, por favor?

Eu tenho o Anaconda3 4.1.1, Python 3.5 e Visual Studio Express 2015 instalado.

É realmente frustrante ...
