python之django- celery : TypeError: can only concatenate tuple (not "NoneType") to tuple

我最近开始将 rabbitmq 和 celery 与 django 一起使用。我正在使用 django-celery、django-celery-email 和邮局以异步方式发送电子邮件。 安装所有这些包后，我的 settings.py 看起来像

INSTALLED_APPS = [ 
#other apps 
'djcelery', 
'djcelery_email', 
'post_office' 
] 
 
 
# setup celery 
import djcelery 
djcelery.setup_loader() 
 
# using post office as the default email backend  
EMAIL_BACKEND = 'post_office.EmailBackend' 
# using djcelery's email backend as a backend for post office  
 
POST_OFFICE_BACKEND = 'djcelery_email.backends.CeleryEmailBackend' 
 
POST_OFFICE = { 
    'DEFAULT_PRIORITY' : 'now' 
} 
 
EMAIL_HOST = 'YOUR_HOST_NAME' 
EMAIL_HOST_USER = "YOUR_HOST_USER_NAME" 
EMAIL_PORT = 25  # default smtp port 
EMAIL_HOST_PASSWORD = "YOUR_HOST_USER_PASSWORD" 
EMAIL_USE_TLS = False 
DEFAULT_FROM_EMAIL = 'testing@example.com' 

当我尝试通过命令运行 django-celery 时

**python manage.py celeryd** 

正在通过以下错误

Traceback (most recent call last): 
  File "manage.py", line 22, in <module> 
    execute_from_command_line(sys.argv)

    worker.get_options() + 
TypeError: can only concatenate tuple (not "NoneType") to tuple 

这里有人帮我解决这个问题

请您参考如下方法:

只需在“~/anaconda2/envs/test_django/lib/python3.6/site-packages/djcelery/management/commands/celery.py”中注释掉这些行，如下所示:

 14     #    options = (CeleryCommand.options + 
 15     #           base.get_options() + 
 16     #           base.preload_options) 

然后就可以了。
