使用PowerShell删除SharePoint Online文件版本控制

Question

当我偶然发现某些PowerShell脚本删除SharePoint Online中文件的某些版本时，我正在寻找一种清理SharePoint的方法，以释放一些空间。假设您的租户设置为具有文件的500版本，您想删除旧文件的版本控制，这些旧文件只是您不想删除，但也不需要500版本。

话虽这么说，我正在努力与SharePoint Online连接，选择了特定的站点，特定的文件，然后删除所有版本。我在Internet上找到了该脚本，并正在对其进行研究，但是似乎我必须具备一些不符合使用该脚本的先决条件。例如，我不了解Add-Type -Path部分，据我所知，此脚本旨在在SharePoint服务器而不是SharePoint Online上运行。

Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"

#Config Parameters
$SiteURL= "https://crescent.sharepoint.com/sites/sales/"
$FileURL="/Sites/Sales/ProjectDocuments/ProjectMetrics.xlsx"

#Setup Credentials to connect
$Cred = Get-Credential
$Cred = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName,$Cred.Password)

Try {
    #Setup the context
    $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
    $Ctx.Credentials = $Cred

    #Get the File
    $File = $Ctx.Web.GetFileByServerRelativeUrl($FileURL)

    #Get all versions of the file
    $Versions = $File.Versions
    $Ctx.Load($Versions)
    $Ctx.ExecuteQuery()

    Write-host -f Yellow "Total Number of Versions Found :" $Versions.count

    #Delete all versions of the file
    $Versions.DeleteAll()
    $Ctx.ExecuteQuery()

    Write-host -f Green "All versions Deleted for given File!"  
}
Catch {
    write-host -f Red "Error deleting versions!" $_.Exception.Message
}

尤其是在使用Get-SPWeb cmdlet时，出现此错误消息：

Get-SPWeb : The term 'Get-SPWeb' 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.

+ Get-SPWeb
+ ~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Get-SPWeb:String) [], CommandNotFoundException

非常感谢您的帮助和澄清，在此先感谢您！

在我这边测试了相同的PowerShell，它可以按预期工作：

在原始问题中的错误消息中，Get-SPWeb用于本地SharePoint而不是SharePoint Online。

对于SharePoint Online，请在此处下载并安装SharePoint Online CSOM：

SharePoint Online Client Components SDK

安装后，PowerShell应该可以正常工作。
