Azure CLI - 硬链接(hard link)失败

Question

我正在尝试下载 Universal Package通过以下方式存储在 Azure DevOps 上:

az artifacts universal download --feed my-feed --name my-cool-package --version 1.0.0 --path Downloads

此包内有一个文件 my-file.dll。我收到的错误是:

Encountered an unexpected error.
System.IO.IOException: Hard linking failed!
 Status: Failed

我能找到的关于此问题的唯一其他实例是 this Github issue ，但这对我解决这个问题没有帮助。

一个有趣的注意事项是，如果我通过将 --path 指定到 C:\ 驱动器上的某个位置来执行该命令，该命令就会成功。当我使用位于外部驱动器上的路径(例如 E:\)执行时，它失败了。

我尝试在管理员 PowerShell 中执行此操作，以排除权限问题，但遇到了相同的错误。我还添加了 --verbose --debug 参数，但我没有看到任何可以帮助我进一步深入研究此问题的信息。

还有其他人遇到过这个问题吗？您对我还有什么其他建议可以尝试在 C:\ 以外的驱动器上成功实现此操作？

Answer 1

当我使用以下 az cli 测试将工件删除到外部驱动器时，我收到与您相同的错误:System.IO.IOException:硬链接(hard link)失败!。目前此问题( Downloading artifact to external drive fails )已在开发者社区论坛上报给产品组进行进一步调查。如果有任何进展，我也会在这里保持同步。
