该位置的应用程序数据文件夹不是普通文件夹。它是一个文件夹 Junction，默认情况下通常是隐藏的。连接存在的唯一原因是将旧应用程序（这些应用程序经过硬编码以查找该文件夹）重定向到 Windows 7 中的新位置。pytest 指向已弃用的“文件夹连接点”似乎很奇怪？怎么解决？
看起来您刚刚安装了（conda 和）pytest 并且想尝试一下，同时位于您的操作系统\users ick 文件夹，包含 pytest 缺乏访问权限的其他隐藏\受保护的操作系统文件夹。我不认为 pytest 故意尝试使用这个已弃用的“文件夹连接”，它只是恰好位于您目前的实际工作文件夹周围。真正运行测试，您会知道在哪里收集它们，即从哪个文件夹执行 pytest。仅用于验证安装，从不包含任何特殊操作系统文件夹的文件夹运行 pytest。
收集测试也称为“测试发现”，可以参数化和/或配置，涉及该主题的 pytest 文档位于此处

python -m pytest [...]
您可以在终端中调用此命令。基本上，通过调用此命令，您可以调用 python 直接运行 pytest，包括将当前目录添加到 sys.path
