      ### Installing Packagers

     ForEach($PackageName in $Packages)
     {
        choco install $PackageName -y
     }

}


    Else
    {
      

       Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]:: SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

       ###### package install stuff ###############

       ForEach($PackageName in $Packages)
       {
            Choco install $PackageName -Y
       }

    }

脚本运行不正常。当我输入任何数字时，软件没有下载，但是当我退出时，软件正在下载如果我的脚本有任何问题，请告诉我怎么做，在我的系统中已经安装了一些软件，但脚本正在下载软件，但在安装脚本期间会给出软件已安装的消息。我需要在我的脚本中设置一些条件，如果软件已经安装在 pc 中，则脚本不应该下载软件，它只应该给出软件已经安装的消息。 请帮助我完成我的任务 谢谢你

谢谢你

好的，我会更改脚本来执行此操作：

# Step 1) install Chocolatey when needed
if (-not (Test-Path -Path "$env:ProgramData\Chocolatey\choco.exe" -PathType Leaf)) {
   # from https://chocolatey.org/install
   Set-ExecutionPolicy Bypass -Scope Process -Force
   [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072
   Invoke-Expression ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1')) 
}

# Step 2) define the array of packages you are offering
$Packages = 'googlechrome','firefox','codeblocks','windbg','nasm',
            'explorersuite','pestudio','vscode','sysinternals','python'

# Step 3) define the Show-Menu function
function Show-Menu {
    Clear-Host
    Write-Host "**********************************************"
    Write-Host "LIST OF SOFTWARES"
    # write the options using the array of packages
    for ($i = 0; $i -lt $Packages.Count; $i++) {
        # {0,2} means right align with spaces to max 2 characters
        Write-Host ('{0,2}. {1}' -f ($i + 1), $Packages[$i])
    }
    Write-Host " q. Exit the script"
    Write-Host "*************************************************"
    Write-Host
}

# Step 4) enter an endless loop you only exit if the user enters 'q'
while ($true) {
    Show-Menu

    $UserInput = Read-Host "Enter the software number to be installed"
    # test if the user wants to quit and if so, break the loop
    if ($UserInput -eq 'q') { break }

    # test if the user entered a number between 1 and the total number of packages (inclusive)
    if ([int]::TryParse($UserInput,[ref]$null) -and 1..$Packages.Count -contains [int]$UserInput) {
        # here you install the chosen package using the array index number (= user input number minus 1)
        $packageIndex = [int]$UserInput - 1
        Write-Host "Installing $($Packages[$packageIndex])"
        choco install $Packages[$packageIndex] -y
    }
    else {
        $availableOptions = 1..$Packages.Count -join ','
        Write-Host "Error in selection, choose $availableOptions or q" -ForegroundColor Red
    }

    $null = Read-Host "Press Enter to continue"
}
