Problem with Trac and Python

[jc@…]

I know that there already were a similar problem but i tested all solutions adviced on your site.

My problem is to access svn with trac. When i read the trac's log, i've the following lines :

Trac[svn_fs] INFO: Failed to load Subversion bindings
Traceback (most recent call last):
  File "build/bdist.macosx-10.5-i386/egg/trac/versioncontrol/svn_fs.py", line 265, in __init__

  Referenced from: /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/libsvn/_fs.so
  Reason: image not found

My system : Mac OSX 10.5.8 with Python 2.5.1 and Subversion 1.6.16

I tried the followings :

sudo port install python_select
sudo python_select python25
sudo port install subversion-python25bindings

and nothing works. With this, i've an Internal Server Error.

Best regards,

It's complaining about /opt/local/lib/libsvn_swig_py25-1.0.dylib

Which should be installed as part of subversion-python25bindings.

What does 'ls -l /opt/local/lib/libsvn_swig_py25-1.0.dylib' say?

Should be:

/opt/local/lib/libsvn_swig_py25-1.0.dylib@ -> libsvn_swig_py25-1.0.0.0.dylib

and /opt/local/lib/libsvn_swig_py25-1.0.0.0.dylib should be there

If not, try uninstalling, cleaning and reinstalling subversion-python25bindings:

sudo port uninstall subversion-python25bindings
sudo port clean --all subversion-python25bindings
sudo port install subversion-python25bindings

Doesn't trac depend on python26 and subversion-python26bindings?

[danielluke (Daniel J. Luke)]

Oh, you're right, it does (and it uses the python26 portgroup, so it should be running setup.py with python26 and not seeing any python25 stuff).

Can you clean and install trac and attach the debug output here?

sudo port uninstall trac
sudo port clean --all trac
sudo port -dv install trac

[jc@…]

Ok.
I tried :

sudo port uninstall trac
sudo port clean --all trac
sudo port -dv install trac

I always have the following error :

Unsupported version control system "svn": dlopen(/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/libsvn/_fs.so, 2): Library not loaded: /opt/local/lib/libsvn_swig_py25-1.0.dylib Referenced from: /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/libsvn/_fs.so Reason: image not found

Then I tried :

python_select python26

I tried on my terminal :

sh-3.2# python
Python 2.6.6 (r266:84292, Apr  1 2011, 10:08:34)

Type "help", "copyright", "credits" or "license" for more information.
>>> from svn import fs
>>> from svn import core
>>>

No problem. But when i relaunched my trac site in browser section :

Unsupported version control system "svn": dlopen(/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/libsvn/_fs.so, 2): Library not loaded: /opt/local/lib/libsvn_swig_py25-1.0.dylib Referenced from: /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/libsvn/_fs.so Reason: image not found

Why does trac try to use python 2.5 so that trac is configured for python 2.6 ?

Best regards,

[danielluke (Daniel J. Luke)]

You didn't post the output of the install command, so it's difficult to know what is happening.

If python_select fixes things, then there is a bug in the port that will be fixed (but it looks like there might be something else going on with your install as well).
