On a Red Hat box, I upgraded Python from 2.3 to 2.6.4 and changed the symlink to python so when I type in python the 2.6.4 interpreter comes up.

However my .py file works from the command-line, but not in the browser. It seemed like a sys.path issue so I opened the file in a browser and printed out sys.path.

Surprisingly, my sys.path is different when called from a browser than when called from a command-line. Because the paths are all referring to 2.3, I believe Apache is picking up Python 2.3 rather than the new 2.6.4 version I installed.

How do I make Apache use Python 2.6.4 rather than 2.3? Both are installed.

You're probably going to need to recompile mod_python. The better solution is to not use mod_python at all. Instead, run your Python applications as FastCGI which will provide you with a much more flexible platform in the long term.

Wow. This is not my server. Any way to do this without rebuilding Apache? – Pranab Dec 10 '09 at 13:09
Use some other method of serving your Python code (i.e. FastCGI) – rodjek Dec 10 '09 at 13:17
I haven't installed FastCGI before - but (apparently the official docs?) say I need to install mod_fastcgi? How do I find if it is installed? – Pranab Dec 10 '09 at 13:26

I'd recommend to install the python2.6 and mod_python 2.6 packages from iuscommunity repository . They are very stable and reliable.

You're assuming that he's using a RedHat based distribution – rodjek Dec 10 '09 at 13:49
I am using RedHat, I did mention in the question. Thank you all, I will go and Google both mod_python and mod_fastcgi later. Right now I solved my original issue by re-installing modules I needed, on Python 2.3. – Pranab Dec 10 '09 at 13:55
Didn't know about IUS, thanks :) – Joril Dec 10 '09 at 15:22
