Question

我正在尝试通过PowerShell安装IIS功能，但无法这样做。如果我运行下面的代码，该脚本将挂起：

VERBOSE: Installation started... 
VERBOSE: Continue with installation?
VERBOSE: Prerequisite processing started...
WARNING: The plug-in for "Web Server (IIS)" is taking more time to load than expected

但是，如果我从控制台运行foreach循环，它就可以工作。这使我相信GUI中的某些内容已将其锁定。有人有什么想法吗？

# Checks to make sure you're running the script in admin mode since the script cannot complete otherwise.
# Bombs out if not otherwise. 
If ( !( [Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()
    ).IsInRole( [Security.Principal.WindowsBuiltInRole]::Administrator ) ) {
    Write-Host "You are not running in an elevated window" -f Red
    Pause
    Exit
}

<#
.SYNOPSIS
    Makes changes to the fonts within the log box on a per amend basis.

.DESCRIPTION
    Makes changes to the fonts within the log box on a per amend basis.

.EXAMPLE
    Write-RichTextBox "Hello World" -colour Blue -Style Italic
    The $FormLogReport richtext box will update with "Hello World" in Blue italic font.

.NOTES
    $formLogReport.ScrollToEnd() will always place the scrollbar at the bottom of the richtext box when a 
    new line is added.
    $form.Dispatcher.Invoke( [Action]{},[Windows.Threading.DispatcherPriority]::ContextIdle ) updates the 
    richtext box on the fly. It's a TRY/CATCH as if the box is refreshed too quickly you'll get errors.

Google并没有提供太多帮助，因此非常感谢您提供一些反馈。谢谢

因此，感谢@RohinSidharth，您的评论支持了GUI引发问题的理论。

我构建了一个功能来“完成”工作，但这还不够，我仍然必须使用Invoke-Command才能使其正常工作。

Function InstallWinFeatures {


   $windowsFeatures = @( "Web-Server", "Web-WebServer", "Web-Common-Http", "Web-Default-Doc", "Web-Static-Content",
"Web-Dir-Browsing", "Web-Http-Errors", "Web-App-Dev", "Web-Asp-Net", "Web-Asp-Net45", "Web-Net-Ext", "Web-Net-Ext45", 
"Web-ISAPI-Ext", "Web-ISAPI-Filter", "Web-Health", "Web-Http-Logging", "Web-Log-Libraries", "Web-Request-Monitor", 
"Web-Http-Tracing", "Web-Security", "Web-Basic-Auth", "Web-Windows-Auth", "Web-Filtering", "Web-Performance", 
"Web-Stat-Compression","Web-Dyn-Compression", "Web-Mgmt-Tools", "Web-Mgmt-Console", "WAS", "WAS-Process-Model", 
"WAS-NET-Environment", "WAS-Config-APIs", "Windows-Identity-Foundation", "NET-HTTP-Activation", "NET-Non-HTTP-Activ", 
"NET-WCF-Pipe-Activation45", "NET-WCF-HTTP-Activation45","Xps-Viewer" )

foreach ( $Feature in $windowsFeatures ) {

    Try {
        Write-RichTextBox "trying to install $feature`r"
        Invoke-Command -ComputerName localhost -ScriptBlock { Install-WindowsFeature -Name $using:Feature -IncludeManagementTools } 
        Write-RichTextBox "Installed $feature`r"
    }
    Catch {
        Write-RichTextBox "Unable to remove $feature`r"
    }
}      
}

如果有人知道为什么会发生这种情况，我将不知所措。谢谢
