Description

The Install-Package cmdlet installs one or more software packages on the local computer. If you have multiple software sources, use Get-PackageProvider and Get-PackageSource to display details about your providers.

Examples

Example 1: Install a package by package name

The Install-Package cmdlet installs a software package and its dependencies.

PS> Install-Package -Name NuGet.Core -Source MyNuGet -Credential Contoso\TestUser

Install-Package uses parameters to specify the packages Name and Source. The Credential parameter uses a domain user account with permissions to install packages. The command prompts you for the user account password.

Example 2: Use Find-Package to install a package

In this example, the object returned by Find-Package is sent down the pipeline and installed by Install-Package.

PS> Find-Package -Name NuGet.Core -Source MyNuGet | Install-Package

Find-Package uses the Name and Source parameters to locate a package. The object is sent down the pipeline and Install-Package installs the package on the local computer.

Example 3: Install packages by specifying a range of versions

Install-Package uses the MinimumVersion and MaximumVersion parameters to specify a range of software versions.

PS> Install-Package -Name NuGet.Core -Source MyNuGet -MinimumVersion 2.8.0 -MaximumVersion 2.9.0

Install-Package uses the Name and Source parameters to find a package. The MinimumVersion and MaximumVersion parameters specify a range of software versions. The highest version in the range is installed.

Notes

Including a package provider in a command can make dynamic parameters available to a cmdlet. Dynamic parameters are specific to a package provider. The Get-Help cmdlet lists a cmdlet's parameter sets and includes the provider's parameter set. For example, Install-Package has the PowerShellGet parameter set that includes -NoPathUpdate, AllowClobber, and SkipPublisherCheck.

Important

As of April 2020, the PowerShell Gallery no longer supports Transport Layer Security (TLS) versions 1.0 and 1.1. If you are not using TLS 1.2 or higher, you will receive an error when trying to access the PowerShell Gallery. Use the following command to ensure you are using TLS 1.2:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
