It doesn't! -- that's precisely why easy_install is free to pick the one that's easier for it. :) >I suppose that any time we select among two distributions with the >same version based on precedence, we should issue a warning, at least >when one of them is a develop dist. That might indeed be doable... at least for tools like buildout and easy_install. I'm not sure it's worth doing so in pkg_resources. >>This was actually more of a happy coincidence than something I >>planned ahead of time, but it does occur in practice. :) > >It made me very unhappy when I first started working with >setuptools.

If you're not installing them with -m, they will be used, because they'll be the one in easy-install.pth. >>Note that in any event, if we make platform-specific eggs have >>higher precedence, then platform-specific built eggs will have to >>take precedence over develop eggs, because "true" develop eggs are >>never viewed as "platform-specific" (because they have no platform >>name in their .egg-info directory name). > >This argument sounds overly pedantic to me. It's actually a comment about the *implementation*. Develop eggs *can't* include version or platform information in their .egg-info directory names, or it makes them useless. _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
