当章鱼部署运行Powershell命令不起作用

我有几个步骤可以解决这个问题，但是我不知道该怎么办。我的最终目标是检查“ app.exe”文件的版本。当我在服务器上手动运行它时，两个脚本版本都可以工作。但是当章鱼运行时，两个版本都会失败，并出现不同的错误

版本1：

  $file = "C:\Octopus\Applications\AppStartUp\38.2.19.0\app.exe"
  $fileVersion = [System.Diagnostics.FileVersionInfo]::GetVersionInfo($file).FileVersion

我得到了错误：

return [System.Diagnostics.FileVersionInfo]::GetVersionInfo <<<< ($file).    FileVersion
    + CategoryInfo          : NotSpecified: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : DotNetMethodException

版本2：

$file = "C:\Octopus\Applications\AppStartUp\38.2.19.0\app.exe"
(Get-Command "$file").FileVersionInfo.Fileversion

错误信息

这些消息的任何Insite以及为什么仅在章鱼中运行时才会发生。
