windows下使用celery启动报错解决

新建tasks.py

import time
from celery import Celery

celery = Celery('tasks', broker='redis://127.0.0.1:6379/0')

@celery.task
def sendmail(mail):
    print(mail)
    print('sending mail to %s...' % mail['to'])
    time.sleep(2.0)
    print('mail sent.')
if __name__ == '__main__':
    pass

celery -A tasks worker --loglevel=info

新建发送邮件模块

from tasks import sendmail
sendmail.delay(dict(to='123@qq.com'))
sendmail.delay(dict(to='456@qq.com'))
sendmail.delay(dict(to='789@qq.com'))
if __name__ == '__main__':
    pass

运行

终端报错

[tasks]
  . tasks.sendmail
