如何在setup.cfg中添加extras_require

setuptools 30.3.0引入了声明性包配置,允许我们将大多数用于直接传递给setuptools.setup文件中setup.cfg的选项。例如,给出以下setup.cfg:

[metadata]
name = hello-world
description = Example of hello world

[options]
zip_safe = False
packages =
  hello_world
install_requires =
  examples
  example1

仅包含

的setup.py.
import setuptools
setuptools.setup()

将做所有正确的事情。

但是,我还没有找到extras_require的正确语法。在setup args中,它是一个字典,如

setup(extras_require={'test': ['faker', 'pytest']})

但我无法找出在setup.cfg中使用的正确语法。我尝试阅读文档,但我无法找到setuptools对字典的正确语法。我也尝试了一些猜测

[options]
extras_require =
  test=faker,pytest

失败了。

Traceback (most recent call last):
  File "./setup.py", line 15, in <module>
    'pylint',
  File "/lib/site-packages/setuptools/__init__.py", line 128, in setup
    _install_setup_requires(attrs)
  File "/lib/site-packages/setuptools/__init__.py", line 121, in _install_setup_requires
    dist.parse_config_files(ignore_option_errors=True)
  File "/lib/python3.6/site-packages/setuptools/dist.py", line 495, in parse_config_files
    self._finalize_requires()
  File "/lib/python3.6/site-packages/setuptools/dist.py", line 419, in _finalize_requires
    for extra in self.extras_require.keys():
AttributeError: 'str' object has no attribute 'keys'

阅读代码,我并非100%确定支持此代码,但基于PEP 508,这似乎应该是受支持的用例。我错过了什么?

支持。您需要配置部分

[options.extras_require]
test = faker; pytest

语法记录为here
