distutils Extension TypeError

Question

最近在学习在Python中扩展C，在 创建setup.py文件的过程中出现了问题

在终端运行“python setup.py build ”命令是出现错误，错误提示为：
[m@localhost CPython]$ python setup.py build
Traceback (most recent call last):
File "setup.py", line 4, in
extest_module = Extension(name = 'Extest', sourses = ['Extest.c'], include_dirs = ['/usr/local/include'])
TypeError: init() takes at least 3 arguments (3 given)

我的 setup.py文件内容：

 #!/usr/bin/env python
from distutils.core import setup, Extension
extest_module = Extension(name = 'Extest', sourses = ['Extest.c'], include_dirs = ['/usr/local/include'])
setup(name = 'Extest', ext_modules = [extest_module])

我的demo主文件内容

#include<stdio.h>

没发现什么大问题，难道是路径错了么？楼主再看看路径和文件都放对这么
