Syntax error in wsgi.py in Apache log files

Question

I'm working on running Django + httpd using mod_wsgi.

I've read up the docs and configured httpd.conf as required. I'm running Python2.7 on Centos5.5

I'm getting a strange "syntax" error which looks like a version conflict to me. Any pointers ?

Here are my Apache error logs:

[Tue Aug 27 19:12:01 2013] [error] [client 10.104.22.85] mod_wsgi (pid=32765): Target WSGI script '/home/sbose/PATH/TO/wsgi.py' cannot be loaded as Python module.

[Tue Aug 27 19:12:01 2013] [error] [client 10.104.22.85]  SyntaxError: invalid syntax

UPDATE: I just figured out that Apache was running Python2.4 Also, FYI,I had installed mod_wsgi with yum.

Thanks.

You might want to see why Target WSGI script '/home/sbose/PATH/TO/wsgi.py' cannot be loaded as Python module error is occuring. May be this post ? — karthikr

Thanks, but this : "ImportError: No module named django.core.handlers.wsgi" is clearly not my case :) — sbose

b strings were introduced between 2.4 and 2.7 (I don't know the exact release).

To check your Python version:

>>> import sys
>>> sys.version
'2.4.4 (#1, Jul 12 2013, 10:47:50) \n[GCC 4.7.3]'

Log it, if you want it to be in your apache log files.

github.com/django/django/blob/master/django/core/handlers/… That's where self.buffer=b' ' is.

Do you even understand this code? Otherwise, b is not a variable defined in the scope, so it must be self.buffer = ''

This is what the b is supposed to be implying stackoverflow.com/questions/6269765/…

What version of Python are you running? It doesn't work in Python 2.4 here, but works in Python 2.7

sbose Over a year ago

I have both installed ( 2.4 was the default ). Any idea how I should be checking which one is being used by Apache?
