SYNOPSIS

Downloads and installs the newest version of specified modules from an online gallery to the local computer.

SYNTAX

Update-Module [[-Name] <String[]>] [-RequiredVersion <Version>] [-MaximumVersion <Version>]
 [-Credential <PSCredential>] [-Proxy <Uri>] [-ProxyCredential <PSCredential>] [-Force] [-WhatIf] [-Confirm]
 [<CommonParameters>]

DESCRIPTION

The Update-Module cmdlet installs a newer version of a Windows PowerShell module that was installed from the online gallery by running Install-Module on the local computer.

By default, the newest version of the specified module available in online gallery is installed, unless you specify a required version. You can update an existing, installed module by specifying the name of the module; Update-Module searches $env:PSModulePath for the module that you want to update.

Running Update-Module without the Name parameter updates all modules that can be updated on the local computer.

EXAMPLES

Example 1: Update all modules

PS C:\> Update-Module

This example updates to the newest version all modules in $env:PSModulePath that were installed by Install-Module from the online gallery.

Example 2: Update a module by name

PS C:\> Update-Module -Name "MyDscModule"

This example updates to the newest online gallery version the first module named MyDscModule found in $env:PSModulePath. If the existing MyDscModule is already the newest version, nothing happens. If Update-Module cannot find a module named MyDscModule in $env:PSModulePath, an error occurs.

Example 3: View what would occur if Update-Module runs

PS C:\> Update-Module -WhatIf
What if: Performing the operation "Update-Module" on target "Version '2.0' of module 'xDscDiagnostics', updating to version '2.0'".
What if: Performing the operation "Update-Module" on target "Version '1.1.1' of module 'xDSCResourceDesigner', updating to version '1.1.1.1'".

This example shows what modules would be updated, and to which versions, if the Update-Module command were actually run. The command is not run.

Example 4: Update a module to a specified version

PS C:\> Update-Module -Name "ContosoModule" -RequiredVersion 2.1.0.3

This example updates ContosoModule to version 2.1.0.3. If version 2.1.0.3 does not exist in the online gallery, an error occurs.

Example 5: Update a module regardless of the current version installed

PS C:\> Update-Module -Name "ContosoModule" -Force

This example installs (or reinstalls) the newest version of ContosoModule from the online gallery, regardless of the current version of the module that is installed on the computer.

NOTES

  • This cmdlet runs on Windows PowerShell 3.0 or later releases of Windows PowerShell, on Windows 7 or Windows 2008 R2 and later releases of Windows.

    If the module that you specify with the Name parameter was not installed by using Install-Module, an error occurs. You can only run Update-Module on modules that you installed from the online gallery by running Install-Module.

    If Update-Module attempts to update binaries that are in use, Update-Module returns an error that identifies the problem processes, and informs the user to retry Update-Module after stopping the processes.
