Question

我正在关注http://flask.pocoo.org/docs/0.12/patterns/celery/

的文档

我收到以下错误。

$ python ./venv/bin/celery -A app.ctasks worker -c 8 -l INFO
[2018-04-19 08:45:03,623: ERROR/MainProcess] Unrecoverable error: TypeError("unhashable type: 'list'",)
Traceback (most recent call last):
File "/Users/andy.terhune/PycharmProjects/flask_socketio_saml/venv/lib/python3.6/site-packages/kombu/utils/__init__.py", line 323, in __get__
return obj.__dict__[self.__name__]
KeyError: 'backend'

我检查了make_celery的行和后端，经纪人是包含正确数据的字符串。

celery = Celery(app.import_name, backend=app.config['CELERY_RESULT_BACKEND'], broker=app.config['CELERY_BROKER_URL'])

我的芹菜设置如下：

cinit.py

from celery import Celery

def make_celery(app):
    celery = Celery(app.import_name, backend=app.config['CELERY_RESULT_BACKEND'], broker=app.config['CELERY_BROKER_URL'])
    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

__init__.py

from flask import Flask,
from flask_socketio import SocketIO
async_mode = None

app = Flask(__name__)
app.config.from_object('config')
socketio = SocketIO(app, async_mode=async_mode)
...
from app import views, socks, saml, helper, cinit
celery = cinit.make_celery(app)
from app import ctasks

我试图以几种不同的方式开始芹菜无济于事。

python ./venv/bin/celery -A app.ctasks worker -c 8 -l INFO

导致：

Unrecoverable error: TypeError("unhashable type: 'list'",)

python ./venv/bin/celery -A app worker -c 8 -l INFO

导致：

AttributeError: 'Flask' object has no attribute 'user_options' 我在这里找到了类似的文章：AttributeError: 'Flask' object has no attribute 'user_options'

和

python ./venv/bin/celery -A app.cinit worker -c 8 -l INFO

导致：

AttributeError: module 'app.cinit' has no attribute 'celery' 这是我所期待的，因为我从未将芹菜设置或导入cinit.py。

有类似的问题必须清除我的后端服务器才能使事情再次运行在我的情况下是redis：

redis-cli FLUSHALL

celery start导致TypeError（“unhashable type：'list'”，）
