Windows PowerShell Posh-SSH 模塊腳本 SFTP 文件上傳到 Linux 服務器給出錯誤

Question

我有下面的 powershell 腳本來執行從 windows 機器到遠程 Linux 服務器的簡單文件上傳。

$DestServerIP = 'xx.xx.xx.xx'
$user = "user"
$pass = "xxxx"
$LocalPath = "\\windows_IP\d$\file.txt"
$RemotePath = '/tmp'

try
{
   $secpasswd = ConvertTo-SecureString $pass -AsPlainText -Force
   $credential = New-Object System.Management.Automation.PSCredential ($user, $secpasswd)
   # Opening a new SFTP session
   $session = New-SFTPSession -ComputerName $DestServerIP -Credential $credential -AcceptKey
   If (($session.Host -ne $DestServerIP) -or !($session.Connected)){
      Write-Host "SFTP server Connectivity failed..!" -ForegroundColor Red
      exit 1
   }
   Write-Host "Session established successfully" -ForegroundColor Green
   Write-Host "Started uploading: $LocalPath files to $RemotePath"

   # uploading all the .txt files to remote server:
   #Set-SFTPItem -SessionId $session.SessionId -Destination $RemotePath -Path ./file.txt
   #Set-SFTPItem -SessionId $session.SessionId -LocalFile $LocalPath -RemotePath $RemotePath -Overwrite -Force
   #Set-SFTPFile -SessionId $session.SessionId -Localfile "D:\file.txt" -RemotePath $RemotePath
   Set-SFTPFile -SessionId ($session).SessionId -LocalFile $LocalPath -RemotePath $RemotePath
   Write-Host "Files successfully uploaded"
} finally {
   Write-Host "Closing the connection" -ForegroundColor Green
   #Disconnect, clean up
   Remove-SFTPSession -SessionId $session.SessionId -Verbose | out-null
   exit 0
} catch {
   Write-Host "Error: $($_.Exception.Message)" -ForegroundColor Red
   exit 1
}

當我使用powershell -F scriptname.ps1運行腳本時，出現以下錯誤

Set-SFTPFile : /tmp does not exist.
At D:\scriptname.ps1:76 char:4
+    Set-SFTPFile -SessionId ($session).SessionId -LocalFile $LocalPath ...

我用Set-SFTPItem替換了它，它也給出了同樣的錯誤

/tmp目錄不可用是由於chroot jail用戶，當我給出可用路徑時，代碼開始工作。
