.egg-cache file stored in the project directory

[stodge@…]

I just installed Trac 0.11.1 on Centos 5.2. I configured Apache (mod_python) and restarted and all looks ok. I can browse ​http://localhost/trac and I see:

Available Projects

    * .egg-cache: Error
      ('module' object has no attribute 'ChangeSet')

But I get an exception when I run trac-admin with no parameters:

trac-admin

Installing Trac 0.11 works fine.

Where (path) did you create your Trac environment ?

[stodge@…]

I hadn't created an environment at this point. I'd forgotten the syntax for the trac-admin command so I ran it with no parameters.

Please don't play with the ticket properties.

Hi,

I have a simular problem:

I'm using Apache with "PythonOption TracEnvParentDir /data/trac". When ich see the project index ther is always

.egg-cache: Error 
([Errno 2] No such file or directory: '/data/trac/.egg-cache/VERSION')

i can delete /data/trac/.egg-cache but it will created again

I believe the issue in comment:6 has been fixed in [7481], which will be included in 0.11.2.

I'm not sure it's the same as the original issue, though. Would it be possible for you to install from the 0.11-stable branch?

The only way I could reproduce the original backtrace:

    from trac.ticket.model import *
AttributeError: 'module' object has no attribute 'ChangeSet'

is by adding 'ChangeSet' to the __all__ list in trac/ticket/model.py …

Somehow that Trac installation got messed up.

As for the problem with the .egg-cache, see comment:7 above.
