重命名项目：无法重命名，因为...处的项目不存在[重复]

我迷失了简单的重命名项目。需要将文件夹名称更改为“01”、“02”、“03”...尝试了所有方法，但最后我得到了“项目不存在”。抱歉问了个愚蠢的问题，但我一整天都在寻找解决方案。

PS C:\Users\admin> 
$nr = 1

Dir E:"Data-test" | %{Rename-Item $_ -NewName (‘{0}’ -f $nr++)}

Rename-Item : Cannot rename because item at 'ert' does not exist.
At line:3 char:23
+ Dir E:"Data-test" | %{Rename-Item $_ -NewName (‘{0}’ -f $nr++)}
+                       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Rename-Item], PSInvalidOperationException
    + FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.RenameItemCommand
 
Rename-Item : Cannot rename because item at 'ukh' does not exist.

user14915444 的有用答案 https://stackoverflow.com/a/65513163/45375提供了关键的指针：

问题是Windows PowerShell情境串连Get-ChildItem (dir) 按文件输出对象name而不是通过完整路径，需要使用$_.FullName而不仅仅是$_; the 问题已解决PowerShell [核心] v6.1+ - see 这个答案 https://stackoverflow.com/a/53400031/45375了解详情。

但是，在您的情况下，通过管道可以完全避免该问题Get-ChildItem output directly to Rename-Item， 用一个延迟绑定脚本块 https://stackoverflow.com/a/52807680/45375，这也加快了操作速度：

[ref] $nr = 1
Get-ChildItem E:Data-test | Rename-Item -NewName { '{0}' -f $nr.Value++ } -WhatIf

^{Note: The -WhatIf common parameter https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_commonparameters#whatif in the command above previews the operation. Remove -WhatIf once you're sure the operation will do what you want.}

请注意使用[ref] https://learn.microsoft.com/en-US/dotnet/api/System.Management.Automation.PSReference变量，它允许从延迟绑定脚本块内部增加输入对象的序列号。这是必要的，因为延迟绑定脚本块在child调用者范围的范围 - 与传递给的脚本块不同ForEach-Object https://learn.microsoft.com/powershell/module/microsoft.powershell.core/foreach-object (%) and Where-Object https://learn.microsoft.com/powershell/module/microsoft.powershell.core/where-object (?).
See GitHub 问题 #7157 https://github.com/PowerShell/PowerShell/issues/7157来讨论这个差异。
