Lets say that have project A, that has requirements B and C < 2. The project B has requirement C >= 1. So, any version of C between 1 and 2 satisfies A (deep) requirements. With url specifiers, I can't specify the version, I need to provide specific version in the link. So, let's say that I have dependency "C @ https://github.com/owner/C.git@3" in project B and "C @ https://github.com/owner/C.git@1" in project A. These are different links and so there is no way to find the version that satisfies both project A and project B requirements. Without version specifiers, I'd need to specify the exact same version in all projects (and if I'm using third party packages, I'm out of luck). I recognize that there is a problem that repository tag may not be the same as python package version. I don't know what to do about it yet. -- Distutils-SIG mailing list -- [email protected] To unsubscribe send an email to [email protected] https://mail.python.org/mailman3/lists/distutils-sig.python.org/ Message archived at https://mail.python.org/archives/list/[email protected]/message/UDLCNRHAWVFMFOKWX73UZ4J2BW4UORZO/
