我一直在创建一个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）。包的结构如下，
rabacus
--setup.py
--README.txt
--MANIFEST.in
--rabacus
----f2py
----python_mod1
----python_mod2
----python_mod3
我在目录f2py中有fortran代码。我的包需要numpy和另一个名为quantity的python包，这两个包都在PyPI中。我已经使用install_requires关键字向setup函数指出了这一点。我的测试周期是这样的，
注册并将包上传到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进行安装
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软件包安装。我很困惑我应该调用哪个设置函数（来自setuptools的那个或来自numpy.distutils.core的那个）。似乎有一个有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作为一项要求并在setup.py脚本中使用numpy？
我的setup.py看起来像这样，
