python - py.test 未启动(EBUSY : [Resource device])

Question

刚刚使用 pip install -U pytest 安装了 py.test 没有错误，但是我们在尝试启动 py.test 时出现错误: EBUSY: [资源设备]: listdir('C:\\Users\\Administrator\\AppData\\Local\\Application Data',)

这是输出:

C:\Users\Administrator>py.test

那会是什么？

谢谢

显然，当 py.test 被调用时，它开始使用 standard test discovery rules 查看文件/文件夹。 .而有些文件夹的访问权限限制了访问，所以会出现这个错误。

要使用 py.test，必须首先导航到包含测试用例的文件夹。
