Nuget，軟件包管理器控制台（PowerShell）問題

Question

在Visual Studio 2012中的Package Manager控制台初始化期間，出現以下錯誤。我在Windows 8上。我找不到在線任何信息，有人遇到相同的問題並找到了解決方案，請告訴我。

謝謝

The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(2977) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject.

The term 'Get-ExecutionPolicy' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

機器上安裝了哪個版本的Visual Studio？ 您是否嘗試以管理員身份運行它？ 您也可以嘗試按照此處的說明啟用Net3.5 @ Powershell運行時
