找不到接受参数“\*”的位置参数

Question

我尝试使用 PowerShell 在 DEV 服务器上安装许多 Web 服务。我想在脚本中包含一个部分，该部分将所有文件和文件夹从暂存区域复制到 DEV 服务器上的相应文件夹。

为了做到这一点，我创建了两个并行字符串数组 - 一个包含暂存文件夹的直接文件路径，另一个包含 DEV 服务器上每个文件夹的名称（我使用了几个其他变量来存储目录的其余部分）。

我想创建一个 for 循环并简单地遍历两个数组以完成 files/folders 从暂存到开发服务器的传输。但是，当循环运行 copy-item 命令时，每次都会出现此错误

Copy-Item : A positional parameter cannot be found that accepts argument '*'.

如果我决定不使用循环，错误就会消失并且文件可以正确传输。刚接触 PowerShell 才几天，所以我不确定发生了什么 on/haven 无法在网上找到与此相关的任何内容。

变量

#web services
$periscopeWebServices = "periscopeWebServices"
$periscopeRetrieveComments = "periscopeRetrieveComments"
$periscopeRetrieveGeneral = "periscopeRetrieveGeneral"
$periscopeRetrieveMasterSubs = "periscopeRetrieveMasterSubs"
$periscopeRetrieveProducers = "periscopeRetrieveProducers"
$periscopeRetrieveProfiles = "periscopeRetrieveProfiles"
$periscopeRetrieveRelationships = "periscopeRetrieveRelationships"
$periscopeSearch = "periscopeSearch"
$periscopeServicesArray = @($periscopeRetrieveComments, $periscopeRetrieveGeneral, 
                            $periscopeRetrieveMasterSubs, $periscopeRetrieveProducers, 
                            $periscopeRetrieveProfiles, $periscopeRetrieveRelationships, 
                            $periscopeSearch)


#staging areas
$stagingComments = "\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveComments"
$stagingGeneral = "\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveGeneral"
$stagingMasterSubs = "\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveMasterSubs"
$stagingProducers = "\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveProducers"
$stagingProfiles = "\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveProfiles"
$stagingRelationships = "\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveRelationships"
$stagingSearch = "\install\PeriscopeServices\periscopeWebServices\periscopeSearch"
$stagingArray = @($stagingComments, $stagingGeneral, $stagingMasterSubs, $stagingProducers
                  $stagingProfiles, $stagingRelationships, $stagingSearch)

#server variables
$domain = "InsideServices.dev.com"
$directory = "E:\webcontent"
$domainpath = "$directory$domain"

循环 - 在 'copy-item'

上抛出错误

#copy files
Write-Host "Copying Files" -ForegroundColor Yellow
For ($i=0; $i -lt $periscopeServicesArray.Length; $i++)
{
    Write-Host "Copying $($periscopeServicesArray[$i])" -ForegroundColor Yellow
    if(Test-Path -path "$domainpath$periscopeWebServices$($periscopeServicesArray[$i])")
    {
        copy-item -Path $($stagingArray[$i])\* -Destination $domainpath$periscopeWebServices$($periscopeServicesArray[$i]) -recurse -Force
    }
}

复制项目命令成功

copy-item -Path $stagingComments\* -Destination $domainpath$periscopeWebServices$periscopeRetrieveComments -recurse -Force

我认为这是因为您在循环内部而不是外部使用了子表达式 $()。试试这些：

"$($stagingArray[$i])\*"

用引号将其括起来使其将整个事物评估为字符串。

$($stagingArray[$i]) + '\*'

这将连接子表达式的结果和包含 \* 的字符串。

找不到接受参数“\*”的位置参数

A positional parameter cannot be found that accepts argument '\*'
