# 【路径兜底】本项目所有模块都用 `from sqlalchemy_fastapi_demo_1.xxx import ...` 导入，

# 这要求「本项目的父目录」在 sys.path 里。直接右键运行 main.py 时 Python 只会把
|

|
|
# sqlalchemy_fastapi_demo_1 自身加入 sys.path，父目录不在其中，就会报

# ModuleNotFoundError: No module named 'sqlalchemy_fastapi_demo_1'。

# 这里主动把父目录补进去，保证 PyCharm 右键运行、命令行、Docker 三种方式都能跑。
