我为此创建了一个可重用的函数。它实际上解析了需求文件的整个目录并将它们设置为 extras_require。
最新的总是在这里可用:https ://gist.github.com/akatrevorjay/293c26fefa24a7b812f5

"""
Parse a glob of requirements and return a dictionary of setup() options.
Create a dictionary that holds your options to setup() and update it using this.
Pass that as kwargs into setup(), viola
Any files that are not a standard option name (ie install, tests, setup) are added to extras_require with their
basename minus ext. An extra key is added to extras_require: 'all', that contains all distinct reqs combined.
Keep in mind all literally contains `all` packages in your extras.
This means if you have conflicting packages across your extras, then you're going to have a bad time.
(don't use all in these cases.)
If you're running this for a Docker build, set `combine=True`.
This will set `install_requires` to all distinct reqs combined.
Example:
>>> import setuptools
>>> _conf = dict(
... name='mainline',
... version='0.0.1',
... description='Mainline',
... author='Trevor Joynson <github@trevor.joynson,io>',
... url='https://trevor.joynson.io',
... namespace_packages=['mainline'],
... packages=setuptools.find_packages(),
... zip_safe=False,
... include_package_data=True,
... )
>>> _conf.update(setup_requirements())
>>> # setuptools.setup(**_conf)
:param str pattern: Glob pattern to find requirements files
:param bool combine: Set True to set install_requires to extras_require['all']
:return dict: Dictionary of parsed setup() options
