How to Install Nuget Package for PowerShell (.nupkg)

By / February 9, 2022

This article shows how to install a PowerShell Nuget Package, and also deploy the same Module to an Offline PC. Install-PackageProvider cmdlet is the first step so that Nuget can be added as a Package Provider, and the Set-PSRepository cmdlet enables to set PSGallery as a trusted source before running Install-Module.

Install-PackageProvider

When you have a PC connected to the internet, first you have to add Nuget as a Package Provider by using Install-PackageProvider.

   Install-PackageProvider -Name NuGet -Force
Run:

After the run, you can see a folder created under C:\Program Files\PackageManagement\ProviderAssemblies\nuget\2.8.5.208

Search a Nuget Package to Install

As an example, I searched SqlServer modules.

Find-Package SqlServer*

Run:

Install Module

Install-Module cmdlet will install the package.

Install-Module SqlServer

However, you may get the following security pop-up.

In order to avoid the pop-up, the Set-PSRepository cmdlet is added to Trust the Repository.

Set-PSRepository PSGallery -InstallationPolicy Trusted
Install-Module SqlServer

Run:

SqlServer was correctly installed.

Offline .nupkg Installation

Search and download the Nuget Package from PSGallery Web Site.

Copy C:\Program Files\PackageManagement\ProviderAssemblies\nuget\2.8.5.208\Microsoft.PackageManagement.NuGetProvider.dll to exactly same folder path location.

Copy downloaded .nupkg file (sqlserver.21.1.18257-preview.nupkg) to a folder (ex. C:\NuPkg)

Register-PSRepository -Name LocalPackages -SourceLocation C:\NuPkg -InstallationPolicy Trusted

Install-Module SqlServer
