OSError: dlopen(libSystem.dylib, 6): image not found

Question

Just updated my Mac to El Capitan 10.11. I am trying to run Django 1.6 with Celery 3.1 and I\'m getting this error now:

Unhandled exception in thread starte         


        

Answer 1

I tried updating to the latest versions of these libraries from github, but it did not help. The simplest solution that I've found is to use virtualenv

virtualenv myenv
cd myenv
source bin/activate
pip install celery

To confirm it worked:

python -c "import celery"

This seems preferable to disabling a fundamental security feature of the OS, and virtualenv has its own (well documented) benefits.
