for some reason, cannot find fastapi in $PATH? thats is supported to be installed with pip no?

[neokuze]

after giving some try i changed the docker-compose.override.yml from fastapi to:

    command:
      - uv
      - run
      - uvicorn
      - app.main:app
      - --reload
      - --host
      - "0.0.0.0"
      - --workers
      - "4"

so this can get closed
