aerich init-db Error: No config named "src.settings"

[Chise1]

When I implemented "aerich init-db",I got an error:No config named "src.settings"
I'm sure my aerich.ini was true.

aerich.ini
[aerich]
tortoise_orm = src.settings.TORTOISE_ORM
location = ./migrations

.This is my folder tree:

├── aerich.ini
├── migrations
├── poetry.lock
├── pyproject.toml
├── src
│   ├── main.py
│   ├── models
│   │   └── init.py
│   └── settings.py
└── tests
└── init.py
