Did you forget to install?

You probably have a mixed setup, the C:\Python23\Lib\site-packages\trac correspond to some older trunk. You're probably running the script from the working directory you've just updated.

After adding in siteconfig.py

__default_plugins_dir__ = 'plugins'

all works but this is not correct. I don't know Trac architecture to understand bug and fix.

Your supposed to do a python setup.py install after an svn update or checkout. By doing that, the trac/siteconfig.py file will be generated automatically.

Yes i do python setup.py install after an svn update or checkout. But after it siteconfig.py does'nt contain default_plugins_dir definitions. Why this variable is present. I think that plugins dir is individual for each project. And there no need to define global path to plugins like to master Trac templates.

Replying to mou@msx.ru:

Yes i do python setup.py install after an svn update or checkout. But after it siteconfig.py does'nt contain __default_plugins_dir__ definitions.

From your checkout path look in "build/lib/trac.siteconfig.py" for the definition of the plugins dir. Also check your "setup.py" file for the presence of __default_plugins_dir__ in the content it writes to siteconfig.py.

Why this variable is present. I think that plugins dir is individual for each project. And there no need to define global path to plugins like to master Trac templates.

Yes, plugins can be installed for a single project, but we also added a global plugins directory to make it easier to install plugins that you intend to use in multiple projects.

This ticket was about an user installation issue, not a problem with Trac. As the New Ticket warning says, installation issues should rather be headed to the MailingList first.

Do not change the status of a ticket without providing some details about the reason for this change.

Encountered the very same problem, but when using the win32 installer.

1. Did a trunk checkout, then generated the installer.
2. Deleted previous site-packages/trac and share/trac files
3. Kicked the installer which went fine.
4. Then, when trying to trac-admin upgrade, encountered the trace mentionned in this ticket.

I guess the problem lies in trunk/scripts/trac-postinstall.py which does NOT contain the 'plugins' stuff.

Reopening and setting to 0.10, sorry for the noise if I'm wrong.
