如何在 PyPi setup.py 文件中包含 .exe、apt-get 和 brew 安装文件

Question

我正在编写一个 setup.py 文件来安装一个使用 PyPi 包的开源项目。问题是，这个项目还需要安装外部应用程序(ghostscript、imagemagick和tesseract(。这些应用程序有不同的安装方式，具体取决于平台(win、Linux 或 mac(。

我写了一个文件，当我执行时python setup.py install安装所有文件。问题是当我在PyPi上加载tar和whl文件并执行pip install Gap-ML它只是在安装模块而不是安装这些应用程序时。

这里的代码 setup.py：

""" setup Gap-ML

from setuptools import setup, find_packages
from distutils.command.install import install

"""

#extract the app_name.exe from the url
app = url.split('/')[-1]

因为您将轮子 (.whl( 文件上传到 PyPI，所以pip install ...将从该轮子安装，并且轮子不会以任何方式支持您尝试执行的操作。 从理论上讲，您可以通过仅将.tar.gz或.zip文件上传到 PyPI 来使其"工作"，以便 pip 从中安装，但这需要用户始终以管理员权限安装您的软件包，这是一个坏主意，违背了推荐的做法并且并不总是有效(例如，用户将无法在 virtualenv 中安装您的软件包(。 正确的做法是不要在setup.py中安装任何系统软件包;相反，请在项目的自述文件中记录所需的包以及如何安装它们。
