Question

我正在尝试从命令行检查芹菜结果但是出现No Result Backend Configured错误。我已将redis设置为我的结果后端，现在我不知所措。

我有这样的芹菜应用程序设置：

qflow/celery.py：

os.environ.setdefault('CELERY_CONFIG_MODULE', 'qflow.celeryconfig')

app = Celery(
    'qflow',
    include=['qflow.tasks']
)
app.config_from_envvar('CELERY_CONFIG_MODULE')

配置模块（qflow/celeryconfig.py）如下所示：

broker_url = 'redis://localhost:6379/0'
result_backend = 'redis://localhost:6379/0'
result_persistent = True
task_result_expires = None
send_events = True

芹菜工人很好：

$ celery -A qflow worker -E -l info

                .> celery           exchange=celery(direct) key=celery

似乎表明结果已配置。

我导入任务并从我的webapp启动它们（基于falcon，使用gunicorn运行），但当我尝试使用celery result <task_id>在命令行上查询时，我得到：

我在linux上运行（4.8.0-52-generic）

Celery：没有配置后端后端？
