故障使用调用命令与脚本块和-ArgumentList

Question

我是新来的PowerShell和想不通，为什么我收到以下错误

调用命令：位置参数无法找到接受参数 “d ：\部署\ file.zip”。 在d：\源\脚本\内置部署\内建部署\ ServersDeploy.ps1：105焦炭：5

• 调用命令-ComputerName $服务器-ScriptBlock {
• ~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  • CategoryInfo：InvalidArgument：（:) [调用-命令]，ParameterBindingException
  • FullyQualifiedErrorId：PositionalParameterNotFound，Microsoft.PowerShell.Commands.InvokeCommandCommand

这是脚本正在运行

params([string[[]]$servers, [string]$dest_package_path, [string]$src_package_path,[string]$deploy_script) 

Invoke-Command -ComputerName $servers -ScriptBlock { 
    param($dest_package_path,$src_package_path,$deploy_script) 
    Write-Output "Destination path = $dest_package_path" 
    Write-Output "Copying zip $src_package_path to the destination host" 
    New-Item -ItemType Directory -Force -Path $dest_package_path 
    Write-Output "Directory Created" 
    Copy-Item -Path $src_package_path -Destination $dest_package_path -Force   

    Write-Host "Copying remote deploy scripts to the destination host" 
    Copy-Item -Path $deploy_script -Destination $dest_package_path -Force 
} -ArgumentList $dest_package_path $src_package_path $deploy_script

因为你用空格代替逗号分隔的参数。这使他们新的论点Invoke-Command。

-ArgumentList接受一个阵列中的单个参数：

Invoke-Command -ComputerName $servers -ScriptBlock { 
    # Stuff 
} -ArgumentList $dest_package_path,$src_package_path,$deploy_script
