我目前正在尝试将更大的代码库从Python 3.8更新到Python 3.11。我使用pyenv来管理我的Python版本，使用poetry来管理我的依赖项:
pyenv local 3.11.3
poetry update
当我运行pytest时，我立即得到:
python -m pytest -n 1

我不知道这是从哪里来的
卸载pytest-django时，至少可以启动pytest。然而，在一个相关的项目中，一切都工作得很好——包括同一版本的pytest-djanog。
升级到Python 3.9工作，但升级到3.10(和3.11)失败。
我该如何调查这个问题?
依赖倡导者似乎是原因。我不知道它是如何使pytest失败的——这与Python 2的兼容性有关。
我是通过grep-ingVendorAlias的虚拟环境找到它的
