# coding: utf-8

from celery import Celery
from flask import Flask

def make_celery(app):
    celery = Celery(app.import_name, broker=app.config['CELERY_BROKER_URL'], backend=app.config['CELERY_RESULT_BACKEND'])
    celery.conf.update(app.config)
    TaskBase = celery.Task
    class ContextTask(TaskBase):
        abstract = True
        def __call__(self, *args, **kwargs):
            with app.app_context():
                return TaskBase.__call__(self, *args, **kwargs)
    celery.Task = ContextTask
    return celery

app = Flask(__name__)
app.config.update(
        CELERY_BROKER_URL='amqp://guest@localhost//',
        CELERY_RESULT_BACKEND='amqp://guest@localhost//'
)

celery = make_celery(app)


@celery.task(name='add_together')
def add_together(a, b):
    return a + b

if __name__ == '__main__':
  result = add_together.delay(23, 42)
  result.wait()   

由于你没有提供错误信息，只能改对之后告诉你了
调用celery -A test.celery worker --loglevel=info启动celery,然后用 python test.py调用脚本
