raise RuntimeError（'您需要使用eventlet服务器。'

Question

在我的项目中，我创建了一个app：

website_chat/views.py代码：

async_mode = 'eventlet'

import os

from django.http import HttpResponse
import socketio

basedir = os.path.dirname(os.path.realpath(__file__))
sio = socketio.Server(async_mode=async_mode)
thread = None

website_chat/management/commands/runserver.py：

^{pr2}$

在我的wsgi.py中：

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Qiyun02.settings")

from socketio import Middleware
from website_chat.views import sio
django_app = get_wsgi_application()
application = Middleware(sio, django_app)

但是当我运行服务器时，我得到如下错误：

Traceback (most recent call last):

RuntimeError: You need to use the eventlet server. See the Deployment section of the documentation for more information.

但是在website_chat/views.py中，我配置了：

async_mode = 'eventlet'
sio = socketio.Server(async_mode=async_mode)

为什么我仍然得到这个错误？在

最后，我没有遵循python-socketio的例子，而是像下面这样配置wsgi.py：

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Qyun.settings")

from socketio import Middleware
from website_chat.views import sio
django_app = get_wsgi_application()
application = Middleware(sio, django_app)

#
import eventlet
import eventlet.wsgi
eventlet.wsgi.server(eventlet.listen(('', 8000)), application)

它现在适用于这个问题。端口仍然是8000，现在也可以删除{}。在
