After running celery in my machine, I got this:
Running a worker with superuser privileges when the worker accepts messages serialized with pickle is a very bad idea! If you really want to continue then you have to set the C_FORCE_ROOT environment variable (but please think about this before you do).
Solution 1:
from celery import Celery, platforms app = Celery(‘tasks‘, broker=‘amqp://myuser:passwd@localhost:5672/vhost‘) platforms.C_FORCE_ROOT = True @app.task def add(x, y): return x, y
Solution 2:
export C_FORCE_ROOT="true"
