说明

The Remove-Module cmdlet removes the members of a module, such as cmdlets and functions, from the current session.

If the module includes an assembly (.dll), all members that are implemented by the assembly are removed, but the assembly isn't unloaded.

This cmdlet doesn't uninstall the module or delete it from the computer. It affects only the current PowerShell session.

示例

Example 1: Remove a module

Remove-Module -Name "BitsTransfer"

This command removes the BitsTransfer module from the current session.

Example 2: Remove all modules

Get-Module | Remove-Module

This command removes all modules from the current session.

Example 3: Remove modules by using the pipeline

"FileTransfer", "PSDiagnostics" | Remove-Module -Verbose

VERBOSE: Performing operation "Remove-Module" on Target "filetransfer (Path: 'C:\Windows\system32\WindowsPowerShell\v1.0\Modules\filetransfer\filetransfer.psd1')".
VERBOSE: Performing operation "Remove-Module" on Target "Microsoft.BackgroundIntelligentTransfer.Management (Path: 'C:\Windows\assembly\GAC_MSIL\Microsoft.BackgroundIntelligentTransfer.Management\1.0.0.0__31bf3856ad364e35\Microsoft.BackgroundIntelligentTransfe
r.Management.dll')".
VERBOSE: Performing operation "Remove-Module" on Target "psdiagnostics (Path: 'C:\Windows\system32\WindowsPowerShell\v1.0\Modules\psdiagnostics\psdiagnostics.psd1')".
VERBOSE: Removing imported function 'Start-Trace'.
VERBOSE: Removing imported function 'Stop-Trace'.
VERBOSE: Removing imported function 'Enable-WSManTrace'.
VERBOSE: Removing imported function 'Disable-WSManTrace'.
VERBOSE: Removing imported function 'Enable-PSWSManCombinedTrace'.
VERBOSE: Removing imported function 'Disable-PSWSManCombinedTrace'.
VERBOSE: Removing imported function 'Set-LogProperties'.
VERBOSE: Removing imported function 'Get-LogProperties'.
VERBOSE: Removing imported function 'Enable-PSTrace'.
VERBOSE: Removing imported function 'Disable-PSTrace'.
VERBOSE: Performing operation "Remove-Module" on Target "PSDiagnostics (Path: 'C:\Windows\system32\WindowsPowerShell\v1.0\Modules\psdiagnostics\PSDiagnostics.psm1')".

This command removes the BitsTransfer and PSDiagnostics modules from the current session.

The command uses a pipeline operator (|) to send the module names to Remove-Module. It uses the Verbose common parameter to get detailed information about the members that are removed.

The Verbose messages show the items that are removed. The messages differ because the BitsTransfer module includes an assembly that implements its cmdlets and a nested module with its own assembly. The PSDiagnostics module includes a module script file (.psm1) that exports functions.

Example 4: Remove a module using ModuleInfo

$a = Get-Module BitsTransfer
Remove-Module -ModuleInfo $a

This command uses the ModuleInfo parameter to remove the BitsTransfer module.

Example 5: Using the OnRemove event

When removing a module, there is an event trigger by the module that allows a module to react to being removed and perform some cleanup task, such as freeing resources.

$OnRemoveScript = {
    # perform cleanup
    $cachedSessions | Remove-PSSession
}
$ExecutionContext.SessionState.Module.OnRemove += $OnRemoveScript

$registerEngineEventSplat = @{
    SourceIdentifier = ([System.Management.Automation.PSEngineEvent]::Exiting)
    Action = $OnRemoveScript
}
Register-EngineEvent @registerEngineEventSplat

The $OnRemoveScript variable contains the script block that cleans up the resources. You register the script block by assigning it to $ExecutionContext.SessionState.Module.OnRemove. You can also use Register-EngineEvent to have the script block execute when the PowerShell session ends.

For script-based modules, you would add this code to the .psm1 file or put it in a startup script that is listed in the ScriptsToProcess property of the module manifest.

参数

-Confirm

Prompts you for confirmation before running the cmdlet.

-Force

Indicates that this cmdlet removes read-only modules. By default, Remove-Module removes only read-write modules.

The ReadOnly and ReadWrite values are stored in AccessMode property of a module.

-FullyQualifiedName

The value can be a module name, a full module specification, or a path to a module file.

When the value is a path, the path can be fully qualified or relative. A relative path is resolved relative to the script that contains the using statement.

When the value is a name or module specification, PowerShell searches the PSModulePath for the specified module.

A module specification is a hashtable that has the following keys.

  • ModuleName - Required Specifies the module name.
  • GUID - Optional Specifies the GUID of the module.
  • It's also Required to specify at least one of the three below keys.
    • ModuleVersion - Specifies a minimum acceptable version of the module.
    • MaximumVersion - Specifies the maximum acceptable version of the module.
    • RequiredVersion - Specifies an exact, required version of the module. This can't be used with the other Version keys.

备注

PowerShell includes the following aliases for Remove-Module:

  • All platforms:
    • rmo

When you remove a module, there is an event is triggered that can be used to run some cleanup code. For more details, see Example 5.
