Ich habe eine Neuinstallation von Win10 und Powershell 5.0. Ich habe Update-Hilfe ausgeführt und die meisten Dinge funktionieren gut; Get-Command gibt jedoch eine Nullreferenzausnahme zurück, unabhängig davon, ob ich im regulären Modus oder im erhöhten Modus bin. Ich habe auch versucht, Powershell von Run mit -noprofile auszuführen, und ich bekomme immer noch den gleichen Fehler sowohl im Benutzer- als auch im erhöhten Modus. Hier sind einige weitere Informationen:Powershell 5.0/Windows 10 Get-Command Null Referenz Ausnahme

Nach dem Ausführen von update-Hilfe sowohl Benutzer und erweiterten Modus, das nächste, was ich in Powershell tat, war installieren SQL Power Doc so bin ich nicht sicher, ob das das Problem verursacht, weil ich don‘ t rufen Sie Get-Command vor der Installation ab.
Während der Installation ich diese Befehle erteilt:
Set-ExecutionPolicy RemoteSigned -Force
New-Item -type directory -path "$([Environment]::GetFolderPath([Environment+SpecialFolder]::MyDocuments))\WindowsPowerShell\Modules"
Set-Location "$([Environment]::GetFolderPath([Environment+SpecialFolder]::MyDocuments))\WindowsPowerShell"
Wenn ich Hilfe laufen auf Get-Command - es ohne Fehler funktioniert:
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.

Sieht jemand etwas offensichtlich? Jede Hilfe wird geschätzt.
Nur zur Klarstellung: Sie haben Windows 10 OS frisch installiert, aber nicht manuell versucht, PowerShell 5.0 zu installieren? Seit PS 5 kommt mit 10? – gravity
Das ist richtig. – SFAgitator
Es könnte sich lohnen, das 'Modules'-Verzeichnis vorübergehend umzubenennen und' Get-Command' erneut auszuführen, um zu sehen, ob das behoben wurde. Nachdem ich gesehen habe, dass Sie ein Modul hinzugefügt haben, wette ich, dass es verwandt ist. Wenn das nicht funktioniert, stelle es wieder her und lass es uns wissen ...;) – gravity
