我维护一个开源库xarray,它使用pytest在Travis-CI上运行集成测试。我们使用stack conda安装科学Python。
Earlier today,我们的五个测试版本中的两个(Python 3.5和3.6,但不是Python 2.7或3.4)开始失败,没有明显的原因。 pytest本身失败了,带着神秘的引用:
$ py.test xarray --cov=xarray --cov-config ci/.coveragerc --cov-report term-missing --verbose $EXTRA_FLAGS

ModuleNotFoundError: No module named 'hypothesis.extra.pytestplugin'
对我来说,有些事情让我感到惊讶:
hypothesis.extra.pytestplugin
。我不知道这是从哪里来的。diff
自己build outputs。)如果您对正在发生的事情有任何线索或猜测,我们将非常感谢您的帮助!我甚至不知道在堆栈中哪里提交错误。
答案 0 :(得分:2)
我挖了一下这个:
hypothesis: 3.33.0-py36_0
,pytest
将其作为插件加载hypothesis
的conda版本固定到3.23
可以解决问题。所以,我认为我们可以断定conda-forge建立假设的问题。
conda-forge
页面上有一个未解决的问题:
