Testdriven.io：AWS 上的可扩展 FastAPI 应用程序。 pytest 找不到主模块

Question

当我尝试学习本课程时https://testdriven.io/courses/scalable-fastapi-aws/

我有一些问题。

当我打字时

talk-booking/services/talk_booking $ poetry run pytest tests/integration

出现错误

我检查健康检查 api 工作良好。 127.0.0.1:8000

当我在 main.py 中编写测试代码时，效果很好。

如果我解决了导入问题，那就完美了

您的 PYTHONPATH 环境变量可能未设置。尝试如下设置 -

导出 PYTHONPATH=$PWD
