CD~正在低于错误。

PS HKLM:\> cd ~
cd : Home location for this provider is not set. To set the home location,     call "(get-psprovider 'Registry').Home = 'path'".
At line:1 char:1
+ cd ~
+ ~~~~
+ CategoryInfo          : InvalidOperation: (:) [Set-Location], PSInvalidOperationException
+ FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.SetLocationCommand

为什么会这样?

因为您在注册表中而引发此错误,并且默认情况下它没有主目录。错误消息明确表示,为了设置主目录(即使我没有理由),您需要调用echo date('Y-W', strtotime('2015-12-31'));

之所以如此,是因为PowerShell中没有为Registry Provider分配的Home位置。

默认情况下,在PowerShell中我们有文件系统的主页位置,并且将是加载的用户配置文件的主目录。

PS C:\> Get-PSProvider -PSProvider FileSystem | Select-Object home

Home
----
C:\Users\Admin

对于Registry Provider,Home位置为空

PS C:\> Get-PSProvider -PSProvider Registry | Select-Object home

Home
----

但你可以设置它,

PS C:\> Get-PSProvider -PSProvider Registry | Get-Member


TypeName: System.Management.Automation.ProviderInfo

Name             MemberType Definition
----             ---------- ----------
Equals           Method     bool Equals(System.Object obj)
GetHashCode      Method     int GetHashCode()
GetType          Method     type GetType()

Drives           Property   System.Collections.ObjectModel.Collection    [System.Management.Automation.PSDriveInfo] Drives {get;}
HelpFile         Property   string HelpFile {get;}
Home             Property   string Home {get;set;} # **Can Be SET** .
ImplementingType Property   type ImplementingType {get;}
Module           Property   psmoduleinfo Module {get;}
ModuleName       Property   string ModuleName {get;}
Name             Property   string Name {get;}
PSSnapIn         Property   System.Management.Automation.PSSnapInInfo     PSSnapIn {get;}

您可以这样设置。

PS C:\> $provider = Get-PSProvider -PSProvider Registry
PS C:\> $provider.Home = "HKLM:\"
PS C:\> Get-PSProvider -PSProvider Registry | Select-Object home

Home
----
HKLM:\

PS C:\> cd HKLM:\SOFTWARE\
PS HKLM:\SOFTWARE\> cd ~
PS HKLM:\>
