If they're working, they're working. If you've got a global install of Setuptools, it's fine.. at least until you have to install an app that needs a different version of a package than another app on the system needs. pkg_resources.require() would be great except that many apps including Paster have no place to specify the versions before the modules are imported. You could hack it into the stub executable, but then there's one more problem with installing Pylons apps via setup.py -- it overwrites the stub script. > > This is going to be another of those "dumb users" issues we clashed > > about before. > > Not especially.

The latest proposal is for pkg_resources to go into Python alone, with a minimum download feature if it's run as a script, to download Setuptools or something from PyPI. That'll at least make it more straightforward to install Setuptools, or to use pkg_resources.require out of the box. -- Mike Orr <[EMAIL PROTECTED]> --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
