There's no solution to it. It happens with all Python packages and other versioning systems. The person who wrote 'Pylons>=0.9.6" doesn't know whether 0.9.7 or 0.9.6.2 will be compatible because they haven't been written yet. So he can either be inclusive (>=) and run the risk of breakage, or exclusive (==) and cause a headache when they refuse to work with his upgrade. I guess you'll have to manually change the dependencies from >= to == in setup.py or pkg_resources.require() in the affected packages, and keep track of your changes in case you have to do them again. Or you can bite the bullet and upgrade your app to 0.9.6 now. -- Mike Orr <[EMAIL PROTECTED]> --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
