Powershell 5.0/Windows 10 Get-Command Null 참조 예외

Question

Win10 및 Powershell 5.0을 새로 설치했습니다. 나는 update-help를 실행했고 대부분 잘 동작한다. 그러나 Get-Command는 일반 모드인지 상승 모드인지에 관계없이 null 참조 예외를 반환합니다. 나는 또한 -noprofile을 사용하여 Run from Powershell을 실행하려고 시도했지만 사용자와 상승 모드에서 여전히 동일한 오류가 발생합니다. 여기에 몇 가지 추가 정보는 다음과 같습니다

PS Z:\> help get-command 

NAME 
    Get-Command 

SYNOPSIS 
    Gets all commands. 


SYNTAX 
    Get-Command [[-ArgumentList] [<Object[]>]] [-All] [-FullyQualifiedModule [<ModuleSpecification[]>]] [-ListImported] [-Module [<String[]>]] [-Noun [<String[]>]] [-ParameterName [<String[]>]] [-ParameterType [<PSTypeName[]>]] [-ShowCommandInfo] [-Syntax] [-TotalCount 
    [<Int32>]] [-Verb [<String[]>]] [<CommonParameters>] 

    Get-Command [[-Name] [<String[]>]] [[-ArgumentList] [<Object[]>]] [-All] [-CommandType {Alias | Function | Filter | Cmdlet | ExternalScript | Application | Script | Workflow | Configuration | All}] [-FullyQualifiedModule [<ModuleSpecification[]>]] [-ListImported] 
    [-Module [<String[]>]] [-ParameterName [<String[]>]] [-ParameterType [<PSTypeName[]>]] [-ShowCommandInfo] [-Syntax] [-TotalCount [<Int32>]] [<CommonParameters>] 


DESCRIPTION 
    The Get-Command cmdlet gets all commands that are installed on the computer, including cmdlets, aliases, functions, workflows, filters, scripts, and applications. Get-Command gets the commands from Windows PowerShell modules and snap-ins and commands that were 
    imported from other sessions. To get only commands that have been imported into the current session, use the ListImported parameter. 

    Without parameters, a Get-Command command gets all of the cmdlets, functions, workflows and aliases installed on the computer. A Get-Command * command gets all types of commands, including all of the non-Windows-PowerShell files in the Path environment variable 
    ($env:path), which it lists in the "Application" command type. 

    A Get-Command command that uses the exact name of the command (without wildcard characters) automatically imports the module that contains the command so you can use the command immediately. To enable, disable, and configure automatic importing of modules, use the 
    $PSModuleAutoLoadingPreference preference variable. For more information, see about_Preference_Variables (http://go.microsoft.com/fwlink/?LinkID=113248). 

    Get-Command gets its data directly from the command code, unlike Get-Help, which gets its information from help topics. 

    In Windows PowerShell 2.0, Get-Command gets only commands in current session. It does not get commands from modules that are installed, but not imported. To limit Get-Command in Windows PowerShell 3.0 and later to commands in the current session, use the 
    ListImported parameter. 

    Starting in Windows PowerShell 5.0, results of the Get-Command cmdlet display a Version column by default; a new Version property has been added to the CommandInfo class.

사람이 분명 아무것도 보이지 않음 동안

내가이 명령을 실행, 설치? 어떤 도움을 주셔서 감사합니다.

Answer 1

Modules 디렉토리를 임시로 바꾼 다음 Get-Command을 다시 실행하여 문제가 해결되었는지 확인하는 것이 좋습니다.

(이 솔루션처럼 질문에 위의 코멘트 당, 그것은 보인다.) 저도 같은 문제를 가지고 있기 때문에

Answer 2

난 그냥이 질문을 우연히 발견했다. SQL Powerdoc 솔루션과 함께 제공되는 모듈 RDS-Manager와 관련이 있다고 생각합니다. RDS.Manager는 TechNet 갤러리에서 제공합니다. http://gallery.technet.microsoft.com/ScriptCenter/e8c3af96-db10-45b0-88e3-328f087a8700/

모듈 폴더에서 전체 폴더를 제거했으며 모든 것이 정상이었습니다. RDS 모듈이 추가되었으며 NullReference Exception이 다시있었습니다.
