Question

下面是我用来将文件夹从TFS 2013 Update 4下载到我的本地计算机的PowerShell脚本，但是我收到了一些我在代码下面复制的异常。

$AutoDeployDir = "$/Intel/Installscript/Utility Scripts"
$deployDirectory = "C:\powershell scripts\New folder\Demo TFS Code"

# Add TFS 2013 dlls so we can download some files
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.Client")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.VersionControl.Client")
$tfsCollectionUrl = "http://stptfs2013dbsvr:8080/tfs/intelcollection"
$tfsCollection = New-Object -TypeName Microsoft.TeamFoundation.Client.TfsTeamProjectCollection -ArgumentList $tfsCollectionUrl
$tfsVersionControl = $tfsCollection.GetService([Microsoft.TeamFoundation.VersionControl.Client.VersionControlServer])

# Register PowerShell commands
Add-PSSnapin Microsoft.TeamFoundation.PowerShell

# Get all directories and files in the AutoDeploy directory
$items = Get-TfsChildItem $AutoDeployDir -Recurse -Server $tfsCollection

# Download each item to a specific destination
foreach ($item in $items) {
    # Serverpath of the item
    Write-Host "TFS item to download:" $($item.ServerItem) -ForegroundColor Blue

    $destinationPath = $item.ServerItem.Replace($AutoDeployDir, $deployDirectory)
    Write-Host "Download to" $([IO.Path]::GetFullPath($destinationPath)) -ForegroundColor Blue

    if ($item.ItemType -eq "Folder") {
        New-Item $([IO.Path]::GetFullPath($destinationPath)) -ItemType Directory -Force
    }
    else {
        # Download the file (not folder) to destination directory
        $tfsVersionControl.DownloadFile($item.ServerItem, $([IO.Path]::GetFullPath($destinationPath)))
    }
}

发生的异常是：

Add-PSSnapin : The Windows PowerShell snap-in 'Microsoft.TeamFoundation.PowerShell' is not installed on this computer.

请确保您已完全安装TFS Powertools。

默认情况下，它不会安装 PowerShell CmdLets 。如果是，只需安装它然后问题就会消失。

另一种可能性是PowerShell管理单元存储在操作系统版本（32位/ 64位）的不一致注册表中。

PowerTools安装程序是32位，在64位机器上，它会写入 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\PowerShell\1\PowerShellSnapIns，但不是 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns.
