Sanic example is not working

I get an error when starting tortoise-orm along with Sanic as an example Python 3.6 from this source https://github.com/tortoise/tortoise-orm/blob/develop/examples/sanic/main.py 1 - I installed everything according to the instructions. The package required installation separately

Friend, I’m very sorry. I finally got enough sleep and realized that I had a mistake while installing orm. I started an empty project, deleted all unnecessary dependencies and it worked;) Thank you very much for spending your time on me!

Why do I need to install Tortoise separately
