PowerShell Add-Type错误：无效的搜索路径

Question

通过从开始菜单或PowerShell ISE中启动PowerShell来运行此代码时，效果很好，但是当我在自定义构建步骤中从Visual Studio内部运行PowerShell时，会出现错误。

$Signature = '
[DllImport("user32.dll")] public static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow);
[DllImport("user32.dll")] public static extern int SetForegroundWindow(IntPtr hwnd);
'

if ($Maximize) { $nCmdShow = 3 } else { $nCmdShow = 1 }
$pInvoke = Add-Type -MemberDefinition $Signature -Name WindowAPI -PassThru

错误：

Add-Type : (0) : Warning as Error: Invalid search path 'C:\Program Files (x86)\Microsoft Visual

Studio\2019\Enterprise\VC\Tools\MSVC\14.27.29110\atlmfc\lib\x64' specified in 'LIB environment variable' -- 'The

请帮助！
