Powershell: How do I install the Nuget provider for PowerShell on a unconnected machine so I can install a nuget package from the PS command line?

Although I've tried all the previous answers, only the following one worked out:

1 - Open Powershell (as Admin)

2 - Run:

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

3 - Run:

Install-PackageProvider -Name NuGet

I accepted trebleCode's answer, but I wanted to provide a bit more detail regarding the steps I took to install the nupkg of interest pswindowsupdate.2.0.0.4.nupkg on my unconnected Win 7 machine by way of following trebleCode's answer.

First: after digging around a bit, I think I found the MS docs that trebleCode refers to:

Bootstrap the NuGet provider and NuGet.exe

Install-PackageProvider

To continue, as trebleCode stated, I did the following

Install NuGet provider on my connected machine

On a connected machine (Win 10 machine), from the PS command line, I ran Install-PackageProvider -Name NuGet -RequiredVersion 2.8.5.208 -Force. The Nuget software was obtained from the 'Net and installed on my local connected machine.

After the install I found the NuGet provider software at C:\Program Files\PackageManagement\ProviderAssemblies (Note: the folder name \ProviderAssemblies as opposed to \ReferenceAssemblies was the one minor difference relative to trebleCode's answer.

The provider software is in a folder structure like this:

C:\Program Files\PackageManagement\ProviderAssemblies   \NuGet      \2.8.5.208         \Microsoft.PackageManagement.NuGetProvider.dll     

Install NuGet provider on my unconnected machine

I copied the \NuGet folder (and all its children) from the connected machine onto a thumb drive and copied it to C:\Program Files\PackageManagement\ProviderAssemblies on my unconnected (Win 7) machine

I started PS (v5) on my unconnected (Win 7) machine and ran Import-PackageProvider -Name NuGet -RequiredVersion 2.8.5.208 to import the provider to the current PowerShell session.

I ran Get-PackageProvider -ListAvailable and saw this (NuGet appears where it was not present before):

Create local repository on my unconnected machine

On unconnected (Win 7) machine, I created a folder to serve as my PS repository (say, c:\users\foo\Documents\PSRepository)

I registered the repo: Register-PSRepository -Name fooPsRepository -SourceLocation c:\users\foo\Documents\PSRepository -InstallationPolicy Trusted

Install the NuGet package

I obtained and copied the nupkg pswindowsupdate.2.0.0.4.nupkg to c:\users\foo\Documents\PSRepository on my unconnected Win7 machine

I learned the name of the module by executing Find-Module -Repository fooPsRepository

Version    Name                                Repository           Description                                                                                                                      -------    ----                                ----------           -----------                                                                                                                      2.0.0.4    PSWindowsUpdate                     fooPsRepository      This module contain functions to manage Windows Update Client.

I installed the module by executing Install-Module -Name pswindowsupdate

I verified the module installed by executing Get-Command –module PSWindowsUpdate

I think I'm good to go

MSDocs state this for your scenario:

In order to execute the first time, PackageManagement requires an internet connection to download the Nuget package provider. However, if your computer does not have an internet connection and you need to use the Nuget or PowerShellGet provider, you can download them on another computer and copy them to your target computer. Use the following steps to do this:

1. Run Install-PackageProvider -Name NuGet -RequiredVersion 2.8.5.201 -Force to install the provider from a computer with an internet connection.

2. After the install, you can find the provider installed in $env:ProgramFiles\PackageManagement\ReferenceAssemblies\\\<ProviderName\>\\\<ProviderVersion\> or $env:LOCALAPPDATA\PackageManagement\ProviderAssemblies\\\<ProviderName\>\\\<ProviderVersion\>.

3. Place the folder, which in this case is the Nuget folder, in the corresponding location on your target computer. If your target computer is a Nano server, you need to run Install-PackageProvider from Nano Server to download the correct Nuget binaries.

4. Restart PowerShell to auto-load the package provider. Alternatively, run Get-PackageProvider -ListAvailable to list all the package providers available on the computer. Then use Import-PackageProvider -Name NuGet -RequiredVersion 2.8.5.201 to import the provider to the current Windows PowerShell session.
