Python Django : No module named security

Question

When I deploy my project on an Ubuntu Server, using a virtualenv, I got this error :

[17/Sep/2014 22:29:00] \"GET / HTTP/1.1\" 500 59
Traceback (most recent          


        

Answer 1

If you previously used a virtualenv for this project make sure that you activate it for the next time that you will use this project source bin/activate or check to see that you use the proper version of django.

If you want to remove some middlewares then you need to make sure of what you are doing.

Answer 2

I guess this happen in django version 1.7.x when you are trying to open project created using django version higher than 1.7.x

removing 'django.middleware.security.SecurityMiddleware' helps but it create another problem 'session error' or something

to fix this:

pip uninstall django==1.7.x //your current version of django installed
pip install django==1.9.x //or version that is compatible with the project
