Description

Update-PSResource downloads and installs the newest version of a package already installed on the local machine. This cmdlet replaces the Update-Module and Update-Script cmdlets from PowerShellGet v2. The new version of the resource is installed side-by-side with previous versions in a new versioned folder.

By default, Update-PSResource installs the latest version of the package and any of its dependencies without deleting the older versions installed. There is no command to uninstall older versions of a package. You must manually delete the files and folders of the older versions.

Update-PSResource doesn't load the updated module into the current session. You must import the new version or start a new session to use the updated module. For more information, see Import-Module.

Examples

Example 1

In this example, the user already has the TestModule package installed and they update the package.

Get-PSResource -Name "TestModule"

-AuthenticodeCheck

Validates signed files and catalog files on Windows.

Type:	SwitchParameter
Position:	Named

-Credential

Specifies optional credentials used when accessing a private repository.

Type:	PSCredential

-Force

When specified, bypasses checks for TrustRepository and AcceptLicense and updates the package.

Type:	SwitchParameter
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Name

Specifies the name of one or more resources to update. Wildcards are supported but NuGet only accepts the * character. NuGet doesn't support wildcard searches of local (file-based) repositories.

Type:	String[]
Position:	0
Default value:	"*"
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	True

-PassThru

When specified, outputs a PSResourceInfo object for the saved resource.

Type:	SwitchParameter
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Prerelease

When specified, allows updating to a prerelease version.

Type:	SwitchParameter
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Quiet

Suppresses progress information.

Type:	SwitchParameter
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Repository

Specifies one or more repository names to search. If not specified, search includes all registered repositories, in priority order (highest first), until a repository is found that contains the package. Repositories are sorted by priority then by name. Lower Priority values have a higher precedence.

When searching for resources across multiple repositories, the PSResourceGet cmdlets search the repositories using this sort order. Update-PSResource updates the first matching package from the sorted list of repositories.

The parameter supports the * wildcard character. If you specify multiple repositories, all names must include or omit the wildcard character. You can't specify a mix of names with and without wildcards.

Type:	String[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	True

-Scope

Specifies the installation scope. Accepted values are:

• CurrentUser
• AllUsers

The default scope is CurrentUser, which doesn't require elevation.

Type:	Microsoft.PowerShell.PSResourceGet.UtilClasses.ScopeType
Accepted values:	CurrentUser, AllUsers
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-SkipDependencyCheck

Skips the check for resource dependencies. This means that only named resources are updated.

Type:	SwitchParameter
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-TemporaryPath

Specifies the path to temporarily install the resource before actual installatoin. If no temporary path is provided, the resource is temporarily installed in the current user's temporary folder.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-TrustRepository

Suppress prompts to trust repository. The prompt to trust repository only occurs if the repository isn't configured as trusted.

Type:	SwitchParameter
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Version

Specifies the version of the resource to be returned. The value can be an exact version or a version range using the NuGet versioning syntax.

For more information about NuGet version ranges, see Package versioning.

PowerShellGet supports all but the minimum inclusive version listed in the NuGet version range documentation. Using 1.0.0.0 as the version doesn't yield versions 1.0.0.0 and higher (minimum inclusive range). Instead, the value is considered to be the required version. To search for a minimum inclusive range, use [1.0.0.0, ] as the version range.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	True

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet isn't run.

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

Inputs

String[]

Outputs

Microsoft.PowerShell.PSResourceGet.UtilClasses.PSResourceInfo
