Installation Error

[John Lee]

0. My environment is Windows Server 2008, Visual SVN Server, Trac 0.11.6.

1. I installed using python egg file (worklog-0.2-py2.5) via Trac's web admin and added "worklog.* = enabled" to trac.ini (in the [components] subheading)

2. When I ran "trac-admin /path/to/projenv upgrade", I got following message.

3. Trac site displays "Work Log" mainnav menu but in that page saying

Ooops.
Trac detected an internal error:
AttributeError: 'Environement' object has no attribute 'get_read_db'

4. Python traceback says

Any help or suggestion will be appreciated.

Thanks in advance.

Hello.

Sorry for the late reply.

The get_read_db() function is used in Trac 0.12. I have looked in the 0.11 version of the plugin and I cannot find this function call, so I suspect you are using the plugin from the 0.12 branch with a 0.11 version of Trac. Please use the code form the 0.11 branch :)

Hope this helps.
