任何人都可以使用Django渠道帮助我解决此错误

Question

我正在使用渠道开发聊天应用程序。这是链接to the documentation。

当我尝试与Redis通信时。它给出了这个错误。安装了该库。逐步实施文档并得到此错误。

>>> import channels.layers
>>> channel_layer = channels.layers.get_channel_layer()
>>> from asgiref.sync import async_to_sync
>>> async_to_sync(channel_layer.send)('test_channel', {'type': 'hello'})
