Question

我有这个脚本。但是运行脚本时出现此错误。

Write-Host：无法将参数'ForegroundColor'绑定到目标。例外设定 “ ForegroundColor”：“由于枚举值，无法将null转换为类型” System.ConsoleColor“ 无效的。指定以下枚举值之一，然后重试。可能的枚举值是“黑色，深蓝色，深绿色，深青色，深红色，深洋红色，深黄色，灰色，深 kGray，蓝色，绿色，青色，红色，洋红色，黄色，白色”。在C：\ Scripts \ DA \ volCheck.ps1：49 char：33 +写主机$ _ -ForegroundColor $ color + ~~~~~~ + CategoryInfo：WriteError：（:) [Write-Host]，ParameterBindingException + FullyQualifiedErrorId：ParameterBindingFailed，Microsoft.PowerShell.Commands.WriteHostComm 和

请帮助，非常感谢。
