如何修复此 AttributeError：“SubRequest”对象没有属性“getfuncargvalue”？

Question

我正在 Mongo 大学参加 MongoDB for Python Developers 课程，但尝试在计算机 mac 上运行 pytest -m 连接时遇到了这个问题：

tests/test_db_connection.py EEEE [100%]

Answer 1

根据您的错误消息，您使用的是 Python3.7。

您可能正在使用已弃用的getfuncargvalue 而不是getfixturevalue，如here 所述。

Answer 2

同样的事情发生在我身上。我将 attrs==19.1.0 添加到 requirements.txt 并且它起作用了！

Answer 3

尝试更新项目的依赖，Pytest、pymongo和Flask的默认依赖都比较老了。更新后我设法让测试通过了。
