为什么无法在云运行中运行没有价值名称的应用程序？

Question

我在部署的云运行https://cloud.google.com/run/docs/quickstarts/build-and-deploy上遇到问题

我已完成本教程中的所有操作，但出现错误

ModuleNotFoundError: No module named 'app'
at import_app (/usr/local/lib/python3.7/site-packages/gunicorn/util.py:350)
at load_wsgiapp (/usr/local/lib/python3.7/site-packages/gunicorn/app/wsgiapp.py:41)
at load (/usr/local/lib/python3.7/site-packages/gunicorn/app/wsgiapp.py:52)

at spawn_worker (/usr/local/lib/python3.7/site-packages/gunicorn/arbiter.py:583)

有关此错误的任何建议？
