ImproperlyConfigured: Error importing middleware treeio.core.middleware.user

Question

I got this error:

[Mon Apr 22 23:45:42 2013] [error] [client 192.168.1.88] mod_wsgi (pid=19481): Exception occurred processing WSGI script '/home/projects/treeio/treeio.wsgi'.

I have Django 1.5.1 and Python 2.7.3. I am trying to install Tree.io.

Any suggest?

Answer 1

Check your Django version, treeio works with Django 1.3.You can change to 1.3 version writing

sudo pip install Django==1.3

Or you can work with virtualenv.

Answer 2

You include treeio.core.middleware.domain.DomainMiddleware before django.middleware.csrf.CsrfViewMiddleware. django.middleware.csrf.CsrfViewMiddleware should be in the list before treeio
