Docker-compose - 模塊導入問題

Question

我正在開發 Flask 應用程序，而我的docker-compose.yml無法找到我的配置文件夾。 我在每個級別都有__init__.py文件，我嘗試從docker-compose.yml文件中添加/刪除配置路徑，但仍然是同樣的問題。 這是我的項目結構：

.
├── ...
├── web_messaging                    
│   ├── app.py 
│   ├── __init__.py        
│   ├── ...       
│   └── config 
│       ├── settings.py 
│       ├── gunicorn.py
│       └── __init__.py
│            
├── __init__py             
├── .env             
├── requirements.txt              
├── docker-compose.yml
└── Dockerfile

當我運行docker-compose up --build時，我收到此錯誤：

website_1  | - 'config' not found.
website_1  | 
website_1  | Original exception:
website_1  | 
website_1  | ModuleNotFoundError: No module named 'config'

docker-compose.yml

version: '2'

services:
  website:
    build: .
    command: >
      gunicorn -c "python:web_messaging.config.gunicorn" --reload "web_messaging.app:create_app()"
    env_file:
      - '.env'
    volumes:
      - '.:/web_messaging'
    ports:
      - '8000:8000'

應用程序.py

def create_app(settings_override=None):
    """
    Create a Flask application using the app factory pattern.

    :param settings_override: Override settings
    :return: Flask app
    """
    app = Flask(__name__, instance_relative_config=True)

    app.config.from_object('config.settings')
    app.config.from_pyfile('settings.py', silent=True)

    if settings_override:
        app.config.update(settings_override)

    error_templates(app)
    app.register_blueprint(user)
    app.register_blueprint(texting)
    extensions(app)
    configure_context_processors(app)
    return app
...

Dockerfile

FROM python:3.7.5-slim-buster

RUN apt-get update && apt-get install -qq -y \
  build-essential libpq-dev --no-install-recommends

ENV INSTALL_PATH /web_messaging
RUN mkdir -p $INSTALL_PATH

WORKDIR $INSTALL_PATH

COPY requirements.txt requirements.txt
RUN pip install -r requirements.txt

COPY . .

CMD gunicorn -c "python:web_messaging.config.gunicorn" "web_messaging.app:create_app()"

看來我解決了。 config文件夾必須在main_messaging文件夾之外，
