對此感到很沮喪，幾天來一直試圖讓它發揮作用。我請求幫助。這是一個包含 Postgres、Celery 和 Docker 的 Django 項目。首先我嘗試使用RabbitMQ，出現了與現在Redis相同的錯誤，然后我多次嘗試后換成redis，錯誤仍然相同，所以我認為問題出在Celery上，而不是RabbitMQ/Redis上。Dockerfile：FROM python:3.8.5-alpineENV PYTHONUNBUFFERED 1RUN apk update \    # psycopg2 dependencies    && apk add --virtual build-deps gcc python3-dev musl-dev \    && apk add postgresql-dev \    # Pillow dependencies    && apk add jpeg-dev zlib-dev freetype-dev lcms2-dev openjpeg-dev tiff-dev tk-dev tcl-dev \    # Translation dependencies    && apk add gettext \    # CFFI dependencies    && apk add libffi-dev py-cffi \    && apk add --no-cache openssl-dev libffi-dev \    && apk add --no-cache --virtual .pynacl_deps build-base python3-dev libffi-devRUN mkdir /appWORKDIR /appCOPY requirements.txt /app/RUN pip install -r requirements.txtCOPY . /app/docker-compose.yml：version: '3'volumes:  local_postgres_data: {}services:  postgres:    image: postgres    environment:      - POSTGRES_DB=postgres      - POSTGRES_USER=postgres      - POSTGRES_PASSWORD=postgres    volumes:      - local_postgres_data:/var/lib/postgresql/data    env_file:      - ./.envs/.postgres  django: &django    build: .    command: python manage.py runserver 0.0.0.0:8000    volumes:      - .:/app/    ports:      - "8000:8000"    depends_on:      - postgres  redis:    image: redis:6.0.8  celeryworker:    <<: *django    image: pyrty_celeryworker    depends_on:      - redis      - postgres    ports: []    command: celery -A pyrty worker -l INFO  celerybeat:    <<: *django    image: pyrty_celerybeat    depends_on:      - redis      - postgres    ports: []    command: celery -A pyrty beat -l INFO
