如何在egg安装期间用Cython构建c扩展

Question

我可以使用以下命令成功安装DMSL包

git clone git://github.com/dasacc22/dmsl.git
cd dmsl
sudo python setup.py install

但是当我尝试安装pip

时

pip install -e git+git://github.com/dasacc22/dmsl.git#egg=dmsl

我得到一个错误

我该如何解决这个问题?

EDIT1:

我已经fork了repo并更正了MANIFEST.in，所以在我的repo中它有

recursive-include dmsl *.html *.dmsl *.c

查找*.html和*.html。dmsl，但问题是没有*.c文件，我需要用Cython创建。我已经安装了这个包，但是作为一个python新手，我需要被引导到下一步。我应该怎样制作c文件?我需要在MANIFEST.in或setup.py中添加其他东西吗?

EDIT2:

我在freenode#python上得到了一些帮助。伙计们建议用python setup.py build_ext制作c文件，并将它们添加到repo中。能避免这种情况就好了。是否有一种方法来运行build_ext命令自动与pip install ?

仅供参考:这类问题值得访问freenode#pip。在那里你可能会幸运地找到jezdez;)

安装Pyrex后，安装工作为我。您可能希望将Cython和Pyrex添加到setup()调用的installd_requires参数中。
