Powershell 我的脚本在ISE中运行，但在控制台中出错

我的脚本在ISE中运行，但是当我想在cmd中运行它时，或者右键单击我的脚本文件并使用

Powershell运行时，我会收到一条错误消息。

我使用的是Windows7，我的Powershell版本是Powershell 2.0

已尝试执行

powershell.exe -STA -FILE "C:\Users\Mgtspare\Documents\Conversion\Conversion_Script.ps1"

我的脚本：

### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "C:\Users\Mgtspare\Downloads"
$watcher.Filter = "*.xls"
$watcher.IncludeSubdirectories = $false
$watcher.EnableRaisingEvents = $true  

### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
$action = { 
            $watcher.Path *.xls | rename-item -newname { [io.path]::ChangeExtension($_.name, "xlsx") }
          }    
### DECIDE WHICH EVENTS SHOULD BE WATCHED 
Register-ObjectEvent $watcher "Created" -Action $action
while ($true) {sleep 5}

错误消息：

### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "C:\Users\Mgtspare\Downloads"
$watcher.Filter = "*.xls"
$watcher.IncludeSubdirectories = $false
$watcher.EnableRaisingEvents = $true  

### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
$action = { 
            $watcher.Path *.xls | rename-item -newname { [io.path]::ChangeExtension($_.name, "xlsx") }
          }    
### DECIDE WHICH EVENTS SHOULD BE WATCHED 
Register-ObjectEvent $watcher "Created" -Action $action
while ($true) {sleep 5}

必须在“*”运算符的右侧提供值表达式

$watcher.Path是我脚本的问题，我更改了脚本。如果有人需要，您可以在下面看到解决方案：

### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
    $watcher = New-Object System.IO.FileSystemWatcher
    $watcher.Path = "C:\Users\Mgtspare\Downloads"
    #$watcher.Filter = "*.*"
    $watcher.IncludeSubdirectories = $true
    $watcher.EnableRaisingEvents = $true

### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
    $action = { 
                Get-ChildItem -Path C:\Users\Mgtspare\Downloads *.xls | rename-item -newname { [io.path]::ChangeExtension($_.name, "xlsx") }
              }

### DECIDE WHICH EVENTS SHOULD BE WATCHED 
    Register-ObjectEvent $watcher 'Created' -SourceIdentifier 'FileCreated' -Action $action
    while ($true) {sleep 5}

$watcher.Path*.xls
无效。也许您只是想通过管道将属性导入命令
$watcher.Path | rename item…..
我发现解决方案$watcher.Path是问题所在：）
