问题描述
我们在 bitbucket 管道中为我们的 python 存储库执行单元测试。最近,我们开始使用 pytest-xdist (https://pypi.org/project/pytest-xdist/) 包,并通过 coverage run -m pytest -n auto
命令在本地运行时成功地并行运行我们的单元测试。这会在我们本地机器上的所有可用 cpu 上执行所有单元测试。但是,当我们通过 bitbucket 管道使用相同的命令运行测试时,我们会遇到以下异常。有没有关于如何解决这个问题的建议?

在此先感谢您的帮助!
解决方法
我遇到了同样的问题,但在将 pytest 升级到 6.2.2
发现问题!
我正在运行旧版本的 pytest。固定最新版本的 pytest(在撰写本文时是 pytest==6.2.2
到我的 requirements.txt
解决了这个问题。随后的问题也是 more-itertools
包没有内置到 python 环境中我配置的 bitbucket 管道容器也将其固定在要求中
