linux 上的 powercli 脚本无法作为 systemctl 服务运行

Question

我正在尝试创建一个 powercli 脚本 (ps1) 作为 systemctl 服务在 linux 上运行。 使用 pwsh 运行时脚本运行良好。 但是，当我将它变成一项服务时，它会失败，就好像无法识别我在脚本中使用的 pwsh 命令一样。

[Unit]
Description=test
After=network-online.target

[Service]
user=root
ExecStart=/usr/bin/pwsh /build/test/test.ps1

[Install]
WantedBy=multi-user.target

我在 journalctl 中看到的错误：

Connect-VIServer: /build/test.ps1:7

(7.2.4:A:80) [NamedPipeIPC_ServerListenerError:NamedPipe.Exception.Error] An error has occurred in PowerShell IPC listening thread on process: 61158 in AppDomain: None.  Error Message: Operation canceled.

为什么这个 pwsh 脚本可以正常运行，但作为 systemctl 服务执行时却失败了？

我设法解决它。 显然，问题出在这一行：服务定义文件中的user=root 。 user应该大写： User 。 所以它没有以 root 身份运行它，因此无法访问模块。
