Dear All, I try to install Zope 2.7.0 in my machine. This version is installed successfully but after the installation I try to run zope service using runzope command. But I got below error. I am using gobolinux and Python 2.3.3 for this zope version. I try to install some other zope version eg (2.7.6,2.8.0 and 3.0.0) all the different version of zope have the same problem. Kindly let me know what is the problem of zope installation. Actually I try to start zope service from the zope instance's bin directory. This instance directory is created by mkzopeinstance.py regards Prabahar gobo@prabahar /Users/enmail/tes]bin/runzope ------ 2005-07-25T10:39:52 INFO(0) ZServer HTTP server started at Mon Jul 25 10:39:52 2005 Hostname: localhost.localdomain Port: 8080 ------ 2005-07-25T10:39:52 INFO(0) ZServer FTP server started at Mon Jul 25 10:39:52 2005 Hostname: prabahar Port: 8021 ------ 2005-07-25T10:39:52 INFO(0) Zope Set effective user to "enmail" Traceback (most recent call last): File "/Programs/Zope/2.7.0/lib/python/Zope/Startup/run.py", line 49, in ? run() File "/Programs/Zope/2.7.0/lib/python/Zope/Startup/run.py", line 19, in run start_zope(opts.configroot) File "/Programs/Zope/2.7.0/lib/python/Zope/Startup/__init__.py", line 51, in start_zope starter.startZope() File "/Programs/Zope/2.7.0/lib/python/Zope/Startup/__init__.py", line 230, in startZope Zope.startup() File "/Programs/Zope/2.7.0/lib/python/Zope/__init__.py", line 45, in startup from Zope.App.startup import startup as _startup File "/Programs/Zope/2.7.0/lib/python/Zope/App/startup.py", line 30, in ? import OFS.Application File "/Programs/Zope/2.7.0/lib/python/OFS/Application.py", line 18, in ? import Globals,Folder,os,sys,App.Product, App.ProductRegistry, misc_ File "/Programs/Zope/2.7.0/lib/python/App/Product.py", line 44, in ? from HelpSys.HelpSys import ProductHelp File "/Programs/Zope/2.7.0/lib/python/HelpSys/__init__.py", line 15, in ? import HelpSys File "/Programs/Zope/2.7.0/lib/python/HelpSys/HelpSys.py", line 18, in ? from Products.ZCatalog.ZCatalog import ZCatalog File "/Programs/Zope/2.7.0/lib/python/Products/ZCatalog/__init__.py", line 16, in ? import ZCatalog, Catalog, CatalogAwareness, CatalogPathAwareness, ZClasses File "/Programs/Zope/2.7.0/lib/python/Products/ZCatalog/ZCatalog.py", line 39, in ? from IZCatalog import IZCatalog File "/Programs/Zope/2.7.0/lib/python/Products/ZCatalog/IZCatalog.py", line 236, in ? __doc__ = IZCatalog.__doc__ + __doc__ TypeError: unsupported operand type(s) for +: 'NoneType' and 'NoneType' __________________________________________________________ Free antispam, antivirus and 1GB to save all your messages Only in Yahoo!
