ImportError: No module named pkg_resources

trac-admin fails with this error when using 0.11dev (integrated WebAdmin):

I'm wondering if we should define setuptools as a required tool (currently it's marked optional in TracInstall and does not even appear in one of the TracInstallPlatforms installation guides) or make the Plugins tab in WebAdmin optional and try to import pkg_resource dynamically.

[Noah Kantrowitz (coderanger) <coderanger@…>]

Trac is in the process of moving to use setuptools internally instead of distutils, so starting with 0.11 it will indeed be required.

[Christopher Lenz]

Right, setuptools is a runtime as well as install time dependency starting with 0.11.

[markus]

Does that mean the docs get wontfixed?

[sid]

Shouldn't this be a ticket for 0.11 to update the documents to reflect the new requirement?

[Christian Boos]

Well, I'm pretty sure the doc will make it explicit that setuptools will be required for 0.11; I don't think we need a ticket to remind this, so that's probably why Christopher closed it that way.

If unsure, simply ask him again when he's back in January, in the meantime I'd say we leave this closed.

I would add that you get the same error if you install the on Windows using the installer.
