No module named genshi.builder

[Aikido Guy]

Google wasn't letting me continue my other thread... so I've started a new one. Sorry about that.

In short, I'm not able to load Trac 1.0.11 in my browser... I am getting a Trac error about not being able to load genshi.builder.

However, I have confirmed I am able to load the offending line from command line python.

Any idea how to solve this? I've tried stopping apache and then bringing it up again. I've check my trac log for that project but I don't see anything. Maybe I'm missing something obvious?

Any further help is very much appreciated!

Kindly,

Aikido Guy

You need to use PythonPath directive.

Just curious, what did you change (if anything) to go from ImportError of _markerlib, to ImportError of genshi.builder? Did you find a solution to the problem that was causing an ImportError of _markerlib?

Actually, I did a number of things, including re-installing python2.7 and using the updated pip to upgrade all of my packages. This seems to have gotten me to the ImportError of genshi.builder.

Then, after having a beer and a day's rest (always very helpful!) I came back and the only thing I could think of doing was to change ownership of all files in /usr/local/lib/python2.7/dist-packages/* to www-data:www-data. I reloaded Trac and low and behold, it is now working again!

To be complete, I did not modify the PythonPath directive in mod_python, as I had a python program that was working properly, so I knew that was a red herring. But thank you for the suggestion Jun!

Thank you all! I have been sweating about this all weekend!

With warmest regards... kindly,
