我试图让一个WebSocket为我正在工作的Django项目运行，但我不能让WebSocket连接，这很奇怪，因为我复制了示例聊天应用程序。
settings.py

INSTALLED_APPS = [
    'daphne',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'channels',
    'core',
    'room',
]

ASGI_APPLICATION = 'WeChat.asgi.application'

HTML部分

{% block scripts %}

{{ room.slug|json_script:"json-roomname" }}

<script>
    const roomName = JSON.parse(document.getElementById('json-roomname').textContent);
    const chatSocket = new WebSocket(
        'ws://'
        + window.location.host
        + '/ws/'
        + roomName
        + '/'
    );

    chatSocket.onmessage = function(e){
        console.log('onmessage')
    }

    chatSocket.onclose = function(e){
        console.log('onclose')
    }
</script>
    
{% endblock %}

routing.py

from django.urls import path

from .import consumers

websoscket_urlpatterns =[
    path('ws/<str:room_name>/',consumers.ChatConsumer.as_asgi()),
    
]

asgi.py

import os

from django.core.asgi import get_asgi_application

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter,URLRouter

import room.routing

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'WeChat.settings')

application = ProtocolTypeRouter({
    "http" : get_asgi_application(),
    "websocket" : AuthMiddlewareStack(
        URLRouter(
            room.routing.websoscket_urlpatterns
        )
    )
})

consumers.py

import json

from channels.generic.websocket import AsyncWebsocketConsumer
from asgiref.sync import sync_to_async

class ChatConsumer(AsyncWebsocketConsumer):
    async def connect(self):
        self.room_name = self.scope['url_route']['kwargs']['room_name']
        self.room_group_name = 'chat_%s' % self.room_name
        await self.channel_layer.group_add(
            self.room_group_name,
            self.channel_name
        )

        await self.accept()
    async def disconnect(self):
        await self.channel_layer.group_discard(
            self.room_group_name,
            self.channel_name
        )

我第一次使用WebSocket。我运行Python文件并检查浏览器，但我得到了一个意外的错误，如

Python：64 WebSocket连接到“ws：//localhost：8000/ws/Python/”失败：（匿名）@ Python：64

它显示了（新的WebSocket）下的红线

const chatSocket = new WebSocket('ws://'
       + window.location.host
       + '/ws/'
       + roomName
       + '/'
   );

首先，我得到了这样的错误，然后我运行命令python -m pip install -U channels[“daphne”]，然后我将daphne添加到安装的应用程序。但在那之后，我得到了一个意想不到的错误**ModuleNotFoundError：没有模块名为'daphne'**任何人，请帮助我修复这个错误？
