Shane hi shane, i don't think so. i modified ZConfig/loader.py, lines 203 and following: try: ignored = __import__(package) +print ignored: %r % ignored except ImportError, e: raise ZConfig.SchemaResourceError( could not load package %s: %s % (package, str(e)), filename=file, package=package) pkg = sys.modules[package] +print pkg: %r % pkg if not hasattr(pkg, __path__): raise ZConfig.SchemaResourceError( import name does not refer to a package, filename=file, package=package) return package:%s:%s % (package, file) the debug prints: ignored: module 'ZODB' from '/home/xlhost/zope/lib/python2.4/site-packages/ZODB3-3.9.0a12-py2.4-linux-i686.egg/ZODB/__init__.pyc' pkg: module 'ZODB' from '/home/xlhost/zope/lib/python2.4/site-packages/ZODB3-3.9.0a12-py2.4-linux-i686.egg/ZODB/__init__.pyc' ignored: module 'relstorage' from '/home/xlhost/zope/lib/python2.4/site-packages/RelStorage-1.1.3-py2.4.egg/relstorage/relstorage.pyc' pkg: module 'relstorage' from '/home/xlhost/zope/lib/python2.4/site-packages/RelStorage-1.1.3-py2.4.egg/relstorage/relstorage.pyc' so the imports seem to work fine, however pkg has __path__ attribute missing! maybe that will help with debugging? btw. i also tried relstorage trunk (did a svn co and replace the egg's files with the checkout files), but that did NOT help. best regards, jürgen herrmann -- XLhost.de - eXperts in Linux hosting ® XLhost.de GmbH Jürgen Herrmann, Geschäftsführer Boelckestrasse 21, 93051 Regensburg, Germany Geschäftsführer: Volker Geith, Jürgen Herrmann Registriert unter: HRB9918 Umsatzsteuer-Identifikationsnummer: DE245931218 Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)700 XLHOSTDE [0700 95467833] WEB: http://www.XLhost.de IRC: #xlh...@irc.quakenet.org ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
[Zope-dev] zope2.12.a04 / relstorage / zodbconvert.py errors
i successfully installed zope 2.12.0a4 via easy_install today.
startup and functionality is fine.
i installed relstorage via easy_install also, but shipped zodbconvert.py
fails with the following traceback:

ZConfig.SchemaResourceError: import name does not refer to a package
Package name: 'relstorage'
File name: 'component.xml'
Package path: None
a debug print before the exception is raised revealed the following:
- a __import__('relstorage') on line 204 of ZConfig/loader.py loads the
module just fine.
- the test hasattr(pkg, __path__) on line 211 fails.
- a __import__('relstorage') in my virtualenv's python interpreter imports
the module and there it has a __path__ attribute!
in a newsgroup posting i read the following sentence:
modules don't have __path__, only packages do. wtf???
his is as much information as i can provide. i'm somehow lost and confused now.
any hints?
thanks in advance and best regards!
jürgen
