Hi,
when accessing trac with apache, get the following error message:
Warning: Can't synchronize with repository "(default)" (Unsupported
version control system "svn": Can't find an appropriate component,
maybe the corresponding plugin was not enabled? ). Look in the Trac
log for more information.
I am using
QNAP NAS system with NSLU2 Linux
apache 2.2.20-1
svn 1.6.17-1
svn-python 1.6.17-1
trac 0.12.1-1 for python26
python 2.6.7-1
python 2.5.6-1 (installed parallelly)
The web is full of similar cases and I think I have read them all and
tried all the advices in the last week. But nothing seemed to help my
case. Here is what I did:
1) Checked that python can find the svn-python bindings:
> python
Python 2.6.7 (r267:88850, Jun 8 2011, 19:25:58)
[GCC 4.2.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import svn
>>>
2) Added svn-python to python path
Added subversion.pth file to /opt/lib/python2.6/site-packages
Confirmed pythin path by printing it in the trac.wsgi script (see
below)
3) Confirmed that svn module can be loaded from within WSGI module
(see trac.wsgi file below)
---
I don't get any error messages in my apache or trac logs. The error
message is just printed in the web page. How can I track this problem
down?
