[Plone-Users] Plone 3 alpha2 error: No traversable adapter found

[John DeStefano]

I'm having some trouble with a fresh v3alpha2 install on Linux:

When I try to add a "CMF Site" at the Zope root, I get: "('No
traversable adapter found', )"

When I try to add a "Plone Site" at the Zope root, I get:
"('No traversable adapter found', {'extension_profiles': ({'product':
'kupu', 'description': 'Extension profile for Kupu', 'for': , 'title':
'Kupu', 'path': 'plone/profiles/default', 'type': 2, 'id':
'kupu:default'},), 'args': (), 'base_profiles': (), 'default_profile':
'Products.CMFPlone:plone'})"

When I try to check the Zope logs via the ZMI, I get:
"Site Error
An error was encountered while publishing this resource.
Error Type: TraversalError
Error Value: ('No traversable adapter found', {'ignored_exceptions':
('Unauthorized', 'NotFound', 'Redirect'), 'keep_entries': 20,
'copy_to_zlog': True})"

When I start Zope in foreground-debug mode ("zopectl fg"), I see
"ImportError: No module named pkg_resources", as well as an error
about installing Five (which seems already to be installed, according
to Zope) and it crashes (more detail below). If I start Zope normally
("start" instead of "fg"), it starts and I can access the ZMI.

I've included everything I can think of below. I hope someone can
help? Also, if this is the wrong place to post such questions, I
apologize; I tried posting to "setup" but my message was rejected.

Thanks,
~John

Setup steps taken:
Install Python 2.4.4
Install Zope 2.10.2 & create Zope instance
Install Imaging 1.1.6
Install elementtree 1.2.6
Install Plone-3.0 alpha2
Restart Zope

John,
We ran into this problem ourselves this morning. We were able to fix it
by installing setuptools (http://cheeseshop.python.org/pypi/setuptools).

Hope that helps,
Eric

Thanks Eric. I've installed the package (I think), but I'm not quite
clear on what do to next in order to troubleshoot this Plone issue.
Do you use easy_install to "upgrade" the Plone packages?

John,
I'm not sure about that. We were able to install from MacPorts and then
just start up Zope/Plone without any problems.

Interesting. So, you didn't install via the official alpha2 tarball
(Plone-3.0-alpha2.tar.gz)?

I've never used this system before, but I assume the syntax would
simply be:
easy_install <package>

If so, when I run that on the tarball, I get:
error: Couldn't find a setup script in Plone-3.0-alpha2.tar.gz

Well, we followed the install.txt for the alpha2 tarball (copy products
to the products folder and the lib to the lib/python folder) without
running easy_install. Install.txt just didn't mention that setuptools
was needed. Once we'd installed setuptools, everything worked just fine.

If I'm following things correctly, Plone is using that itself to
run/install some of the Python eggs in the lib/python folder.

Strangely enough, once I installed setuptools, my Plone stuff also
"Just Worked" and everything is fine. Thanks Eric. Without your
mentioning this, I'm not sure I ever would have gotten up and
running.

Does this mean that everyone else was already aware of this somehow,
or that nobody else is testing alpha2? Unless setuptools isn't truly
necessary, and we're missing something, I think it's worth mentioning
in the installation instructions.

You're quite welcome.

Agreed on the installation instructions. Is this worth adding a ticket
for? Anyone?

+1. I tested 3.0alpha2 a week or so back and ran into exactly the same
problem - not having setuptools and it not being in the installation
instructions. So I agree it should be in the instructions. Whether a
ticket is the way to make that happen, I don't know....

Does anyone know of a Plone 2.1.x compatible Product that provides a report for site usage by login?
