Timeline and Browse Source... No module named svn (modules ARE installed)

[matt.t.galvin@…]

I have gotten everything installed and configured. the trac-admin … initenv can see the svn modules (or else the install would not even work). I can view and use the wiki. When I try to use the Timeline or Browse Source I receive the following error message.

System Specs (with custom builds of all the deps):

• RHEL 3
• Python 2.4.1
• Apache 2
• Subversion 1.2.3

PYTHON_SITE=/usr/local/lib/python2.4/site-packages PYTHONPATH=/usr/local/lib/svn-python/libsvn:/usr/local/lib/svn-python/svn:/usr/local/lib/svn-python

(this is where svn installs it modules now, i could not get them to install into the sitedir)

Please let me know if there is anyother information I can provide that might be helpful.

This is an installation support issue, not a Trac bug, so please ask on the IrcChannel or MailingList if you need help resolving this.

[Matthew Good]

Well, since the trac-admin command worked it appears that you have the PYTHONPATH variable set on the commandline, but not in your Apache config. You will need to use the Apache config option "SetEnv" to configure the PYTHONPATH variable for the Trac application.

As you noted, the Subversion Python bindings are not installed to default location. You need to make them available to Python scripts yourself. There are two ways to do this:

1. Create a .pth file in site-packages:

   $ echo /usr/local/lib/svn-python > /usr/local/lib/python2.4/site-packages
   

2. Use symlinks:

    $ ln -s /usr/local/lib/svn-python/svn /usr/local/lib/python2.4/site-packages/svn
    $ ln -s /usr/local/lib/svn-python/libsvn /usr/local/lib/python2.4/site-packages/libsvn

That first snippet above should've been:

$ echo /usr/local/lib/svn-python > /usr/local/lib/python2.4/site-packages/svn.pth

[matt.t.galvin@…]

I wound up symlinking to the dir with:

ln -s /usr/local/lib/svn-python/svn /usr/local/lib/python2.4/site-packages/svn ln -s /usr/local/lib/svn-python/libsvn /usr/local/lib/python2.4/site-packages/libsvn

which caused it to not be able to find libsvn_swig_py-1.so.0.

I then just re-ran ldconfig and then it worked.

So symlinking and running ldconfig worked for me.

Thanks for the tip and sorry for the noise.

Here's an echo command that will indeed create the .pth file mentioned above. $ echo "/usr/local/lib/svn-python" > /usr/local/lib/python2.4/site- packages/svn-python.pth
