i am running Ubuntu 10.04.1 LTS and it came pre-packed with python2.6 but i need to replace it with python2.7.2. (The reason is simple, 2.7 has a lot of features backported from 3 ) i had installed python2.7.2 using ./configure make make altinstall the altinstall option installed it, without touching the system default version, to /usr/local/lib/python2.7 and placed the interpreter in /usr/local/bin/python2.7 Then to help mod_wsgi find python2.7 i added the following to /etc/apache2/sites-available/wsgisite WSGIPythonHome /usr/local i start apache and run a test wsgi app BUT i am greeted by python 2.6.5 and not Python2.7 Later i replaced the default python simlink to point to python 2.7 ln -f /usr/local/bin/python2.7 /usr/bin/python Now typing 'python' on the console opens python2.7 but somehow mod_wsgi still picks up python2.6 Next i tried, PATH=/usr/local/bin:$PATH export PATH then do a quick restart apache, but yet again its python2.6 !! Here is my $PATH /usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games contents of /etc/apache2/sites-available/wsgisite WSGIPythonHome /usr/local <VirtualHost *:80> ServerName wsgitest.local DocumentRoot /home/wwwhost/pydocs/wsgi <Directory /home/wwwhost/pydocs/wsgi> Order allow,deny Allow from all </Directory> WSGIScriptAlias / /home/wwwhost/pydocs/wsgi/app.wsgi </VirtualHost> app.wsgi import sys def application(environ, start_response): status = '200 OK' output = sys.version response_headers = [('Content-type', 'text/plain'), ('Content-Length', str(len(output)))] start_response(status, response_headers) return [output] Apache error.log 'import site' failed; use -v for traceback [Sun Jun 19 00:27:21 2011] [info] mod_wsgi (pid=23235): Initializing Python.
