In your last post on this issue you said you had alembic 0.7.4 installed already. That doesn't satisfy the requirement for a version 0.6.4. Perhaps you need to uninstall that version, or downgrade to something that meets the requirements? Alternatively - it seems as though you may have a very old version of neutron-rootwrap. I don't know much about Neutron so maybe I'm reading this wrong, but require(\'neutron==2013.2.4.dev32\') suggests old age to me. Perhaps it would be possible to upgrade your version? FWIW, I tested in a virtualenv; with just alembic==0.7.4 installed, pip install -r requirements.txt on a file that contained alembic0.6.4,=0.4.1 was able to downgrade my environment from 0.7.4 to 0.6.3. It seems possible that maybe you could be talking to a PyPi proxy that is missing the older alembic packages, and that adding those packages to the proxy so they can be downloaded might possibly resolve your issue __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
