My docker-compose.yml:

services:
  sass:

    command: sass --watch --style compressed --scss /app/static/styles/scss/style.scss:/app/static/styles/style.css

on earlier versions of 1.7 and 1.8 I get the same error ...

Did you set a custom COMPOSE_PROJECT_NAME? If not, what is the name of the folder containing your docker-compose.yml file?

I did not set COMPOSE_PROJECT_NAME. And it's not the name of the directory from which you launch...

I think I know what the problem is. The problem is that the directory is called the Russian character "Проект"...

Thanks for the help!
