Yeah, we don't support zipped eggs for migrations, since you can't discover what migrations there are inside them easily, if at all. You should set this in your ~/.distutils.cfg:

[easy_install]
zip_ok = False

That will install all packages unzipped.

[admin@…]

Can't you just ignore that error then?

[andrew]

We probably could - if you want that feature, open a new bug for it. I'd much rather recommend people don't use zipped eggs at all, as they play havoc in all kinds of ways (when you're on read-only filesystems, for example)

Try uninstalling the egg and then reinstalling with the easy_install flag "--always-unzip".

$ pip uninstall <package>
$ easy_install --always-unzip <package>
