You could also add setup_requires=[“docutils”], and then pass in a Distclass (defined in your setup.py) and/or custom cmdclass entries which delay the import until the body of the methods on those classes. This should be after the setup_requires code has ran so the docutils import should work. --- Donald Stufft PGP: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
