对于powershell函数和调用exe函数，您需要稍微不同的错误处理，并且您需要确保告诉脚本的调用者它失败了。构建在Psake库的Exec之上，具有下面结构的脚本将在所有错误时停止，并可作为大多数脚本的基本模板。

Set-StrictMode -Version latest
$ErrorActionPreference = "Stop"


# Taken from psake https://github.com/psake/psake
<#
.SYNOPSIS
  This is a helper function that runs a scriptblock and checks the PS variable $lastexitcode
  to see if an error occcured. If an error is detected then an exception is thrown.
  This function allows you to run command-line programs without having to
  explicitly check the $lastexitcode variable.
.EXAMPLE
  exec { svn info $repository_trunk } "Error executing SVN. Please verify SVN command-line client is installed"
#>
function Exec
{
    [CmdletBinding()]
    param(
        [Parameter(Position=0,Mandatory=1)][scriptblock]$cmd,
        [Parameter(Position=1,Mandatory=0)][string]$errorMessage = ("Error executing command {0}" -f $cmd)
    )
    & $cmd
    if ($lastexitcode -ne 0) {
        throw ("Exec: " + $errorMessage)
    }
}

Try {

    # Put all your stuff inside here!

    # powershell functions called as normal and try..catch reports errors 
    New-Object System.Net.WebClient

    # call exe's and check their exit code using Exec
    Exec { setup.exe }

} Catch {
    # tell the caller it has all gone wrong
    $host.SetShouldExit(-1)
    throw
}

看来简单的重掷就行了。

param ([string] $Path, [string] $Find, [string] $Replace)
try {
  ((Get-Content -path $Path -Raw) -replace $Find, $Replace) | Set-Content -Path $Path
  Write-Output Completed.
} catch {
  # Without try/catch block errors don't interrupt program flow.
  throw
}

现在只有在成功执行之后才会出现输出Completed。

$ErrorActionPreference = "Stop"将得到你的部分方式(即这是cmdlets的伟大作品)。

然而，对于EXEs，你需要检查$LastExitCode自己后，每exe调用，并确定是否失败了。不幸的是，我不认为PowerShell可以在这里提供帮助，因为在Windows上，EXEs对于“成功”或“失败”退出码的构成并不是非常一致。大多数遵循UNIX标准，0表示成功，但并非所有都这样做。在这篇博客文章中查看CheckLastExitCode函数。你可能会发现它很有用。

不幸的是，由于有bug的cmdlet，如New-RegKey和Clear-Disk，这些答案都不够。我目前在一个名为ps_support.ps1的文件中确定了以下代码:

Set-StrictMode -Version Latest
$ErrorActionPreference = "Stop"
$PSDefaultParameterValues['*:ErrorAction']='Stop'
function ThrowOnNativeFailure {
    if (-not $?)
    {
        throw 'Native Failure'
    }
}

然后在任何powershell文件中，在文件(如果存在)的CmdletBinding和Param之后，我有以下内容:

$ErrorActionPreference = "Stop"
. "$PSScriptRoot\ps_support.ps1"

重复的ErrorActionPreference = "Stop"行是有意的。如果我犯了错误，以某种方式获得了ps_support的路径。Ps1错了，那需要的不是默默的失败!

我保留ps_support。Ps1位于我的repo/workspace的公共位置，因此点源的路径可能会根据当前. Ps1文件的位置而改变。

任何本地调用都会得到这样的处理:

native_call.exe
ThrowOnNativeFailure

在编写powershell脚本时，使用该文件进行点源可以帮助我保持头脑清醒。: -)

我来这里也是为了寻找同样的东西。$ErrorActionPreference="Stop"立即杀死我的shell时，我宁愿看到错误消息(暂停)之前，它终止。回到我的批处理敏感性:

IF %ERRORLEVEL% NEQ 0 pause & GOTO EOF

我发现这对我的特定ps1脚本几乎是一样的:

Import-PSSession $Session
If ($? -ne "True") {Pause; Exit}
