pypi UserWarning：未知分发选项：“ install_requires” [英] pypi UserWarning: Unknown distribution option: 'install_requires'

问题描述

执行PyPI软件包的 python setup.py install 时，是否会遇到此警告？

Does anybody encounter this warning when executing python setup.py install of a PyPI package?

install_requires 定义软件包的要求。许多PyPI软件包都有此选项。

install_requires defines what the package requires. A lot of PyPI packages have this option. How can it be an "unknown distribution option"?

推荐答案

python setup.py 使用不支持install_requires的distutils。 setuptools这样做，还分发（它的后继），而pip（使用其中一个）做。但是实际上您必须使用它们。即通过 easy_install 命令或 pip install 调用setuptools。

python setup.py uses distutils which doesn't support install_requires. setuptools does, also distribute (its successor), and pip (which uses either) do. But you actually have to use them. I.e. call setuptools through the easy_install command or pip install.

另一种方法是从setup.py中的setuptools导入安装程序，但这不是标准方法，这使得每个想要使用您的软件包的人都必须安装setuptools。

Another way is to import setup from setuptools in your setup.py, but this not standard and makes everybody wanting to use your package have to have setuptools installed.
