创建Alembic迁移时导入的问题

Question

我有这样的文件结构：

├───auth_service
│   ├── alembic
│   │   |___versions
│   │   │___env.py
│   │  
│   |── src
|   |    |___config.py
|   |
|   |___alembic.ini
│  
├───market_service

alembic.ini 文件：

[alembic]
script_location = alembic
prepend_sys_path = .
version_path_separator = os
sqlalchemy.url = .
...

alembic/env.py 文件：

from auth_service.src.config import env_config
from auth_service.src.core.engines.postgres_engine import Base

config = context.config
config.set_main_option('sqlalchemy.url', env_config.postgres_url())

if config.config_file_name is not None:
    fileConfig(config.config_file_name)


target_metadata = Base.metadata


def run_migrations_offline() -> None:
    url = config.get_main_option("sqlalchemy.url")
    context.configure(
        url=url,
        target_metadata=target_metadata,
        literal_binds=True,
        dialect_opts={"paramstyle": "named"},
    )

    with context.begin_transaction():
        context.run_migrations()
...

当我尝试在 .../project/auth_service 目录下运行 alembic revision --autogenerate -m 'text' 命令时，出现了一个错误：

File "C:\Users\user\PycharmProjects\Microservices-FastAPI\auth_service\alembic\env.py", line 8, in <module>
    from auth_service.src.config import env_config
ModuleNotFoundError: No module named 'auth_service'

我试着在所有相关的目录中添加 __init__.py 文件，并把导入路径从：

from auth_service.src.config import env_config
from auth_service.src.core.engines.postgres_engine import Base

改成：

from ..src.config import env_config
from ..src.core.engines.postgres_engine import Base

但这导致我出现了一个错误：

File "C:\Users\user\PycharmProjects\Microservices-FastAPI\auth_service\alembic\env.py", line 8, in <module>
    from ..src.config import env_config
ImportError: attempted relative import with no known parent package
