Question

作为我的问题powershell if-else does not follow either branch的后续跟进，我发现了另一个奇怪的情况。我有一个脚本作为计划任务每天运行一次。只有在作为计划任务运行时才会出现此问题（永远不会从命令提示符，ide或PowerShell窗口运行），甚至只在某些日期运行。相关代码是

$target_dir = "\\server\path\"
$tmpStatus = "init"
$err = $false
try { $tmpStatus = Test-Path ( $target_dir + "receivals.tmp") }
catch
{
    $tmpStatus = $error | foreach { $_.Exception }
    $err = $true
}

有些日子$ tmpStatus会报告问题

System.Management.Automation.CommandNotFoundException: The term 'Test-Path' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
   at System.Management.Automation.ExceptionHandlingOps.CheckActionPreference(FunctionContext funcContext, Exception exception)
   at System.Management.Automation.Interpreter.ActionCallInstruction`2.Run(InterpretedFrame frame)
   at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame)
   at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame)

但是，稍后在同一次运行的同一个脚本中，当我再次使用Test-Path时，它每次运行都很好。 Test-Path如何不是一个有效的命令？

Answer 1

尝试使用限定符：

Microsoft.PowerShell.Management\Test-Path ( $target_dir + "receivals.tmp")

Answer 2

我将此添加到我的构建脚本中。

Import-Module "$env:SystemRoot\System32\WindowsPowerShell\v1.0\Modules\Microsoft.PowerShell.Management\Microsoft.PowerShell.Management.psd1"

powershell Test-Path未被识别为cmdlet
