为了在Django Rest框架中设置安全websocket，我在docker-compose中添加了Daphne。
daphne:
platform: linux/amd64
build:
context: .
dockerfile: Dockerfile.dev
command: 'sh -c "daphne -b 0.0.0.0 -p 8000 apps.asgi:application"'
restart: always
当我打开docker-compose时，我看到了以下错误。如果我从docker-compose中删除daphne条目。Yml，这个错误不会发生。我能够成功地构建组合早先。
