Development server doesn't work on Mac Os with Python-2.4.3

I run the development server with python 2.4.3 :

ibook-g4-de-charlax:~/temp/test/django/test1 ca$ python
Python 2.4.3 (#1, May 25 2006, 02:02:07)

0 errors found.

Django version 0.95 (post-magic-removal), using settings 'test1.settings'
Development server is running at
Quit the server with CONTROL-C.

No error for the moment. Then I load in my browser. I get this error :

Traceback (most recent call last):

    raise exceptions.ImproperlyConfigured, 'Error importing middleware %s: "%s"' % (mw_module, e)

ImproperlyConfigured: Error importing middleware django.middleware.sessions: "No module named sessions"

Then I reload the page, and it works fine, but after each change I won't work until I reload the page.

With Python-2.3 there's no problem.

I think you may need to do a little more digging on this. I'm not seeing any problems running the dev server with a current svn checkout [3069], Python 2.4.3, OS X 10.4.6.

I also use the current svn checkout (3069), Python 2.4.3, OS X 10.4.5
I will dig a bit more, but I really don't see where the problem come from.

Using Django SVN with dev server just fine on OS X 10.4.6 with Python 2.4.3.

What happens if you remove the session middleware from the list of middleware in your

It works fine after removing django.middleware.sessions.SessionMiddleware.

Seems like this is a setup problem, not a Django bug.

Thanks for your help ! Now it works.

It was effectively a setup problem : there was a lot of django version coexisting on my Mac.
