运行与setup.py一起安装的包时找不到依赖项

Question

我正在尝试安装一个程序包，该程序包在安装期间构建了一个名为reaper的c++库，setup.py脚本如下所示：

import subprocess
from setuptools import setup
from setuptools.command.install import install as _install
import os

with open("README.md", "r") as fh:
    long_description = fh.read()

class InstallLocalPackage(_install):
    def run(self):
        _install.run(self)
        reaper_path = os.path.join(os.path.dirname(__file__), 'REAPER')
        subprocess.call("mkdir build", shell=True, cwd=reaper_path)
        subprocess.call("cmake ..", shell=True, cwd=os.path.join(reaper_path, 'build'))
        subprocess.call("make", shell=True, cwd=os.path.join(reaper_path, 'build'))


setup(
    name="reapy",
    version="0.0.1",
    long_description=long_description,
    packages=['reapy'],
    setup_requires=["numpy"],
    install_requires=["numpy"],
    cmdclass={'install': InstallLocalPackage},
    classifiers=[
        "Programming Language :: Python :: 2.7",
        "Programming Language :: Python :: 3.7",
        "Operating System :: UBUNTU",
    ],
)

以下是python setup.py install的终端输出：

然而，当我导入reapy时，我得到一个ModuleNotFoundError：没有名为'numpy'的模块，表明bumpy没有安装。我相信这可能与cmdclass安装调用有关，但不确定如何修复此问题
