我在运行PowerShell时不断收到此错误

Question

当我运行此PowerShell脚本时

Import-Module WebAdministration
$path1 = Get-ItemProperty -PSPath IIS:\Sites\CompassSvcQA-Red\R4\CompassSettings

Set-Location "C:\Windows\Microsoft.NET\Framework\v4.0.30319"
.\aspnet_regiis.exe -pef "connectionStrings" $path1.physicalPath -prov "DataProtectionConfigurationProvider"

我收到此错误：

Get-ItemProperty : Cannot find drive. A drive with the name 'IIS' does not
exist.
