我试图遵循用Cython本教程： http://docs.cython.org/docs/tutorial.html#the-basics-of-cython ，我有一个问题。
该文件是非常简单的。 我有一个helloworld.pyx：
print "Hello World"
和一个setup.py：
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
setup(
cmdclass = {'build_ext': build_ext},
ext_modules = [Extension("helloworld", ["helloworld.pyx"])]
)
和我一起的标准命令编译：
python setup.py build_ext --inplace
我得到了以下错误：
running build
running build_ext
building 'helloworld' extension

我有蟒蛇和Ubuntu 9.04的仓库安装用Cython。 我想不通为什么编译器不能找到Python.h。
我试着这样做：
cython helloworld.pyx
然后用gcc手动编译的结果：
gcc -shared -pthread -fPIC -fwrapv -O2 -Wall -fno-strict-aliasing -I/usr/include/python2.5 -o helloworld.so helloworld.c
并得到了完全相同的错误消息。
任何线索？
