OSError: [Errno 10048] error while attempting to bind on address

OSError: [Errno 10048] error while attempting to bind on address ('0.0.0.0', 8080): only one usage of e
ach socket address (protocol/network address/port) is normally permitted

I have installed aiohttp and as mentioned in a tutorial, I tried to run the script using python main.py command

from aiohttp import web
async def index(request):
    return web.Response(text='Hello Aiohttp!')
app = web.Application()
web.run_app(app)

I get this error and don't know how to sort this issue.

Any kind of help is appreciated

Issue with your problem is some process is already running on 8080 port number. There are two ways to solve problem

  1. sudo kill `sudo lsof -t -i:8080` (if you are working on ubuntu) or sudo kill $(sudo lsof -t -i:8080)

  2. python -m aiohttp.web -H localhost -P 5050 package.module.init_func

    package.module.init_func should be an importable callable that accepts a list of any non-parsed command-line arguments and returns an Application instance after setting it up:

    def init_function(argv):
    app = web.Application()
    app.router.add_route("GET", "/", index_handler)
    return app

hopefully above solution may will help you.

you can go through documentation of aiohttp to know more about it. https://aiohttp.readthedocs.io/en/v0.21.5/web.html

From the documentation https://aiohttp.readthedocs.io/en/stable/web_reference.html#aiohttp.web.run_app .You can pass the port as

from aiohttp import web
async def index(request):
    return web.Response(text='Hello Aiohttp!')
app = web.Application()
web.run_app(app, port=9090)
