我一直在努力创建一个 python 包，其中包含一些我想在 numpy 中使用 f2py 合并的 fortran 代码。目标是将其上传到 PyPI，以便用户可以使用 pip 进行安装。我做了一些研究，发现 setuptools 和 numpy.distutils.core 具有我想要的功能（我认为）。包的结构是这样的，

rabacus  
--setup.py  
--README.txt  
--MANIFEST.in    
--rabacus  
----f2py  
----python_mod1  
----python_mod2  
----python_mod3

我在 f2py 目录中有 fortran 代码。我的包需要 numpy 和另一个名为 quantity 的 python 包，它们都在 PyPI 中。我已经用 install_requires 关键字在 setup 函数中指出了这一点。我的测试周期是这样的，

注册并上传包到 PyPI

python setup.py register sdist upload

创建一个没有系统包的虚拟环境

virtualenv --no-site-packages venv

进入虚拟环境并尝试使用 pip 安装

cd venv/bin  
./pip install rabacus

我希望它检测未满足的要求（numpy 和数量），下载它们，然后继续我的包安装。我对应该调用哪个设置函数（来自 setuptools 的函数或来自 numpy.distutils.core 的函数）感到困惑。似乎一个有 install_requires，一个有 ext_modules。到目前为止，当我在虚拟环境中执行 pip 命令时，我收到一个错误，抱怨找不到 numpy

是否可以将 numpy 作为要求并在 setup.py 脚本中使用 numpy？

我的 setup.py 看起来像这样，

import os
import setuptools 
import numpy.distutils.core
