致命错误：找不到“ mymodule.h”文件-Cython编译无法找到标头

因此，我一直在尝试运行一个简单的脚本，在该脚本中，我在MacOS 10.11.5（El Capitan）下使用Cython 0.24将C代码合并到我的python项目中。我使用PyCharm和Python版本2.7.10编辑代码。我的setup.py看起来像这样

from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
from Cython.Build import cythonize
import os

dirs = [os.getcwd()]

ext  =  [Extension("hello_world",
                   include_dirs=dirs,
                   sources=["mymodule.c","hello_world.pyx"],
                   depends=["mymodule.h"])]
setup(
    name = "testing",
    cmdclass={'build_ext' : build_ext},
    ext_modules = cythonize(ext)
)

它可以很好地生成hello_world.c，还可以生成一个构建目录和一个* .so文件* .pyx文件包含以下定义，该定义显然与mymodule.h中的定义匹配

cdef extern from "mymodule.h":
    cdef float MyFunction(float, float)

我尝试了此处建议的解决方案：安装python库时出现“'cc'失败，退出状态为1”的错误

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

并且上面代码中已经存在的自定义扩展解决方案来自这里：使用C头文件编译Cython错误

我还尝试了此处建议的MacOS特定解决方案，但这简直是绝望：https : //github.com/wesm/feather/issues/61

export MACOSX_DEPLOYMENT_TARGET=10.11

但不幸的是，它仍然无法正常工作。我确信Cython可以正常工作，因为我事先实现了一些功能，当在Cython中实现时可以很好地调用它们。它只是包括实际的C代码，对我而言就是发生此问题的地方。

希望有人能帮助我，在此先感谢！

编辑：我收到以下错误信息
