pythonbrew with mod_wsgi

Question

pythonbrew isn't getting picked up by by mod_wsgi file, config follows:

import os
import sys
import site

site.addsitedir('/home/bharal/.pythonbrew/pythons/Python-2.7.2/lib/python2.7/site-packages')
sys.path.append ('/home/bharal/public_html/dumpstown')

os.environ['DJANGO_SETTINGS_MODULE'] = 'dumpstown.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

and the pythonbrew version of python i want to use is situated here:

/home/bharal/.pythonbrew/pythons/Python-2.7.2/lib/python2.7/site-packages

and my pythonbrew install is here:

/home/bharal/.pythonbrew/

How do i tell mod_wsgi to use this version (2.7.2) and not the default python version that shipped with ubuntu (2.6)?

When i run my server, i get errors like so:

as you can see from the logs, the server is still looking at python 2.6!! Why? I've kicked off pythonbrew so when i type in python i can see the version is 2.7.2, and all the settings and packages i need are importable!

UPDATE as indicated in the answer below, the mod_wsgi doesn't care which python i tell it to use - in fact, i cannot tell it to use any particular python. The only way to do so is to download an uncompiled wsgi file, compile with the particular python version i want, and use the compiled wsgi.

See my other question Error: Command failed with rc=65536 python and mod_wsgi for some of the steps and links to tutes if you like. In the end i didn't compile against 2.7 (my 2.6 was fine and it was too hard to get the pythonbrew compile working)

Answer 1

That particular error has nothing to do with the version of Python used. Use:

sys.path.append ('/home/bharal/public_html') sys.path.append ('/home/bharal/public_html/dumpstown')

To get mod_wsgi to use a specific version, compile it from source code against that version or find a binary package for mod_wsgi compiled against the correct version.
