Issue

Application is a simple chat using django-channels and celery (just tried to substitude Pipenv with poetry for my old app). While managing my deps using Pipenv, everything is OK and i have no issues at all. But while using poetry with exactly same deps list, server can't find websocket via its route and get this error.

```
[06/Oct/2019 22:13:46] "GET /chat1/ HTTP/1.1" 200 8842
Not Found: /ws/chat/chat1/
[06/Oct/2019 22:13:47] "GET /ws/chat/chat1/ HTTP/1.1" 404 2607

Pipenv output:

HTTP GET /chat1/ 200 [0.07, 127.0.0.1:51086]
WebSocket HANDSHAKING /ws/chat/chat1/ [127.0.0.1:51090]
WebSocket CONNECT /ws/chat/chat1/ [127.0.0.1:51090]
```

Here is this app: https://github.com/fly1ngDream/channels-chat (After commit that start using poetry for deps management, sockets became broken). I had tried to use beta version of poetry, but it didn't help

Hi @fly1ngDream,

I see that output formats are quite different, so I assume that in case of poetry you are running your application with runserver which knows nothing about the ASGI_APPLICATION setting in your config and in case of pipenv you are running it in some different way.

However, if you really need some help, please provide clear steps to reproduce the issue.

[yevhenshymotiuk]

@Jamim yea, but i start server exactly the same way. Obviously, server can't recognize ASGI. To reproduce you should start server via runserver, start redis server (redis-server) and start celery worker (celery worker -A config -l info) in a django directory. Then create new chat room and try to connect to it.

@fly1ngDream I've tried what you described with pipenv using code from https://github.com/fly1ngDream/channels-chat/commit/77ba32bc8e945526c02abbd7e4cb2b87497d11ab and it leads to the same results that you got with poetry.

@Jamim Weird. Ill try it again later and give a comment

[yevhenshymotiuk]

Recreated pipenv virtualenv and got same issue. Obviously, poetry is not the source of this issue

[yevhenshymotiuk]

The issue was: i installed the django-channels dependency which has nothing in common with the channels one
