当我执行PowerShell脚本以执行Azure PowerShell的静默安装时,它会抛出此异常:
异常调用" DownloadInstallerFile"用" 2"参数:"传递给此方法的InstallerContext需要一个 非空的Installer文件。" 在行:18 char:5
脚本如下:
[reflection.assembly]::LoadWithPartialName("Microsoft.Web.PlatformInstaller") | Out-Null
$ProductManager = New-Object Microsoft.Web.PlatformInstaller.ProductManager
$ProductManager.Load()
$product = $ProductManager.Products | Where { $_.ProductId -eq "WindowsAzurePowerShell" }
$InstallManager = New-Object Microsoft.Web.PlatformInstaller.InstallManager
$Language = $ProductManager.GetLanguage("en")
$installertouse = $product.GetInstaller($Language)
$installer = New-Object 'System.Collections.Generic.List[Microsoft.Web.PlatformInstaller.Installer]'
$installer.Add($installertouse)
$InstallManager.Load($installer)
$failureReason=$null
foreach ($installerContext in $InstallManager.InstallerContexts) {
$InstallManager.DownloadInstallerFile($installerContext, [ref]$failureReason)
}
$InstallManager.StartInstallation()
我该如何解决这个问题?
