Docker 中 Python 中的 Mapscript 循环导入错误

Question

我有一个简单的烧瓶应用程序，我正在尝试在 Docker 中运行

import mapscript
from flask import Flask
import json

app = Flask(__name__)
port = 5000

@app.route("/hello")
def geocoder():


    epsg = mapscript.pointObj(1, 1)
    return json.dumps(epsg)

    test()

if __name__ == '__main__':
    app.run(host="0.0.0.0", port=port)

我的 Dockerfile 是：

FROM python

WORKDIR /opt/demo/
COPY /app .

RUN pip install -r requirements.txt

ENTRYPOINT python test.py

但是当我运行 docker run -p 5000:5000 test:latest 时出现以下错误：

Traceback (most recent call last):
  File "/opt/demo/test.py", line 1, in <module>
    import mapscript
  File "/usr/local/lib/python3.9/site-packages/mapscript/__init__.py", line 2, in <module>
    from .mapscript import *
  File "/usr/local/lib/python3.9/site-packages/mapscript/mapscript.py", line 13, in <module>
    from . import _mapscript
ImportError: cannot import name '_mapscript' from partially initialized module 'mapscript' (most likely due to a circular import) (/usr/local/lib/python3.9/site-packages/mapscript/__init__.py)

只有当我在 Docker 外部运行时激活了 Python VENV 时才会发生这种情况，但我不知道为什么我在 Docker 内部收到此错误。
