  • The Trac installer no longer includes the ClearSilver library; it needs to be installed separately. You can find binaries at http://www.clearsilver.net/downloads/ or http://clearsilver.yi.org/.
  • If you upgrade from 0.8.x, take care to uninstall 0.8.x first. Otherwise, you'll have a "No module named log" error, because the installer will install the 0.9.x trac/log.py file using the 0.8.x upper case name trac/Log.py (see #2533)

Latest Development Source Code

We use Subversion for source revision control and code sharing.

The Subversion repository URL for the Trac project is at:


Trac devel

The latest revision for the devel version of Trac (currently 0.11dev) can be checked out with the following command:

svn co http://svn.edgewall.org/repos/trac/trunk trac

Or with encryption:

svn co https://svn.edgewall.org/repos/trac/trunk trac

Trac stable

The latest revision for the stable version of Trac (currently Trac 0.10.5dev) can be checked out with the following command:

svn co http://svn.edgewall.org/repos/trac/branches/0.10-stable 0.10.5dev

For installing this version, we recommend that you choose some well visible place (e.g. /opt/trac-0.10.5dev), and override the PYTHONPATH environment variable (or PythonPath path directive for mod_python) by preprending the /opt/trac-0.10.5dev/lib/python2.4/site-packages path (replace 2.4 by the Python version that you actually use). That way, you minimize the risk of interferences with the packaged Trac version you probably already have.

cd 0.10.5dev
python setup.py install --prefix=/opt/trac-0.10.5dev


export PYTHONPATH=/opt/trac-0.10.5dev/lib/python2.4/site-packages:$PYTHONPATH

or, in your httpd.conf:

<Location /projects/myproject>
  PythonPath "['/opt/trac-0.10.5dev/lib/python2.4/site-packages'] + sys.path"


If you already had existing checkouts for svn.edgewall.com, no need to redo the checkouts, you can simply relocate your working copies:

svn switch --relocate http://svn.edgewall.com http://svn.edgewall.org
