Nuget，程序包管理器控制檯（powershell）問題

Question

在Visual Studio 2012的程序包管理器控制檯初始化過程中出現以下錯誤。我在Windows 8上。我無法在線找到任何信息，是否有人遇到過相同的問題並找到了解決方案，請讓我知道。

感謝

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.
