What resolution :). So what happens with pip install -r /opt/stack/new/requirements/global-requirements.txt is that the constraints in that file are all immediately put into pip's state, including oslo.config >= 1.11.0, and then all other constraints that reference to oslo.config are simply ignored. this is 1b (and 2a) on https://github.com/pypa/pip/issues/988. IOW we haven't been testing what we've thought we've been testing. What we've been testing is that 'python setup.py install X' for X in global-requirements.txt works, which sadly doesn't tell us a lot at all. So, as I have a working (but unpolished) resolver, when I try to do the same thing, it chews away at the problem and concludes that no, it can't do it - because its no longer ignoring the additional constraints. To get out of the hole, we might consider using pip-compile now as a warning job - if it can succeed we'll be able to be reasonably confident that pip itself will succeed once the resolver is merged. The resolver I have doesn't preserve the '1b' feature at all at this point, and we're going to need to find a way to separate out 'I want X' from 'I want X and I know better than you', which will let folk get into tasty tasty trouble (like we're in now). -Rob -- Robert Collins <[email protected]> Distinguished Technologist HP Converged Cloud __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: [email protected]?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
