I'm assuming you didn't follow the "conditional dependencies" link from the description in that first paragraph, as it would have taken you to the corresponding section of one: https://www.python.org/dev/peps/pep-0426/#environment-markers You should probably also see: https://www.python.org/dev/peps/pep-0496/ https://www.python.org/dev/peps/pep-0508/#environment-markers Quickly skimming relevant changelogs, environment markers have been supported by Setuptools since 0.7, and directly in requirements lists since pip 6.0. -- Jeremy Stanley _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
