Doc issue with Asphalt usage

[smlbiobot]

Hi—

Same issue with this page: https://mirai.veriny.tf/en/latest/core/asphalt.html#

I can’t actually figure out what is wrong. I put this in my code as what the page asked me to:

from asphalt.core import ContainerComponent, Context
from kyoukai import Kyoukai
from kyoukai import KyoukaiComponent

app = Kyoukai("api")

class AppContainer(ContainerComponent):
    async def start(self, ctx: Context):
        self.add_component(
            'kyoukai', KyoukaiComponent, ip="127.0.0.1", port=4444, app=app)
        await super().start(ctx)

But just get a bunch of error messages and I don’t know how to fix / what is wrong:

[409]:$ asphalt run config.yml
INFO:asphalt.core.runner:Running in development mode

ModuleNotFoundError: No module named 'application'

The above exception was the direct cause of the following exception:

    sys.exit(main())

As an addendum, this is currently the structure of my project folder:

[413]:$ tree
.

Ok I have solved the error, after reading the Asphalt doc, it seems that I have to run this instead:

PYTHONPATH=. asphalt run config.yaml

Reference: Asphalt documentation on how to run config if it’s not in site-packages

...I had that exact answer written in the box, but I must've closed the tab without commenting. Sorry about that.
