我有redis 5.4。我得到了这个错误: aioredis.errors.ReplyError: ERR unknown command 'BZPOPMIN' 我正在关注 django-channels 网站上的教程。这是消费者代码:

class ChatConsumer(WebsocketConsumer):
    def connect(self):
        self.room_name = self.scope['url_route']['kwargs']['room_name']
        self.room_group_name = 'chat_%s' % self.room_name

        # Join room group
        async_to_sync(self.channel_layer.group_add)(
            self.room_group_name,
            self.channel_name
        )

        self.accept()

    def disconnect(self, close_code):
        # Leave room group
        async_to_sync(self.channel_layer.group_discard)(
            self.room_group_name,
            self.channel_name
        )

    # Receive message from WebSocket
    def receive(self, text_data):
        text_data_json = json.loads(text_data)
        message = text_data_json['message']

        # Send message to room group
        async_to_sync(self.channel_layer.group_send)(
            self.room_group_name,
            {
                'type': 'chat_message',
                'message': message
            }
        )

    # Receive message from room group
    def chat_message(self, event):
        message = event['message']

        # Send message to WebSocket
        self.send(text_data=json.dumps({
            'message': message
        }))

我运行我的服务器,python manage.py runserver 0.0.0.0:8080 -- noreload也许它必须做一些事情,我在 5656 端口上打开页面,当我使用 vagrant 时它托管在 8080 上,这些是 VagrantFile 中的设置端口。

编辑 不知道为什么,但如果我在 pip freeze 上检查 redis-server 的版本,我会得到 (.venv) vagrant@vagrant:/vagrant/ChatApp$ redis-server --version Redis server v=4.0.9 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=9435c3c2879311f3,但我不确定为什么会这样以及如何解决这个问题。

I am not sure but the problem may be related to channels-Redis, may be it is not compatible with the version of channels, try downgrading or updating channels-Redis
