py.test 不启动（EBUSY：[资源设备]）

Question

刚刚安装 py.testpip install -U pytest没有错误，但是我们正在尝试启动py.test我收到错误：EBUSY: [Resource device]: listdir('C:\\Users\\Administrator\\AppData\\Local\\Application Data',)

这是输出：

C:\Users\Administrator>py.test

那可能是什么？

谢谢

显然，当py.test被调用时，它开始使用标准测试发现规则查看文件/文件夹。并且某些文件夹具有限制访问的访问权限，因此会发生此错误。

要使用py.test一个必须首先导航到带有测试用例的文件夹。
