pip install from a github repo - 如何在 egg install 期间使用 Cython 构建 C 扩展

Question

我可以使用以下命令成功安装the DMSL package

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

但是当我尝试使用pip安装时

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

我收到一个错误

我该如何解决这个问题？

编辑1：

我已经分叉了 repo 并更正了 MANIFEST.in 所以在我的 repo 中它有

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

它会找到 *.html 和 *.dmsl，但问题是没有 *.c 文件，我需要使用 Cython 创建这些文件。我已经安装了这个包，但是作为一个 python 新手，我需要指导下一步。我应该怎么做才能生成 C 文件？我需要向MANIFEST.in 或setup.py 添加其他内容吗？

编辑2：

我在 freenode#python 上得到了一些帮助。伙计们建议使用python setup.py build_ext 生成C 文件并将它们添加到repo。避免这种情况会很好。有没有办法使用pip install 自动运行 build_ext 命令？

仅供参考：对于此类问题，值得访问 freenode#pip。在那里你可能有幸找到jezdez ;)

安装 Pyrex 后，安装对我有用。您可能希望将 Cython 和 Pyrex 添加到 setup() 调用的 installed_requires 参数中。
