Install NuGet via PowerShell script - powershell

As far as I can tell, NuGet is meant to be installed as a Visual Studio extension:
http://docs.nuget.org/docs/start-here/installing-nuget
But what if I need NuGet on a machine that doesn't have VS installed?
Specifically, I would like to install NuGet with a PowerShell script.

Run Powershell with Admin rights
Type the below PowerShell security protocol command for TLS12:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Here's a short PowerShell script to do what you probably expect:
$sourceNugetExe = "https://dist.nuget.org/win-x86-commandline/latest/nuget.exe"
$targetNugetExe = "$rootPath\nuget.exe"
Invoke-WebRequest $sourceNugetExe -OutFile $targetNugetExe
Set-Alias nuget $targetNugetExe -Scope Global -Verbose
Note that Invoke-WebRequest cmdlet arrived with PowerShell v3.0. This article gives the idea.

This also seems to do it.
PS Example:
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force

Without having Visual Studio, you can grab Nuget from: http://nuget.org/nuget.exe
For command-line executions using this, check out: http://docs.nuget.org/docs/reference/command-line-reference
With respect to Powershell, just copy the nuget.exe to the machine. No installation required, just execute it using commands from the above documentation.

With PowerShell but without the need to create a script:
Invoke-WebRequest https://dist.nuget.org/win-x86-commandline/latest/nuget.exe -OutFile Nuget.exe

None of the above solutions worked for me, I found an article that explained the issue. The security protocols on the system were deprecated and therefore displayed an error message that no match was found for the ProviderPackage.
Here is a the basic steps for upgrading your security protocols:
Run both cmdlets to set .NET Framework strong cryptography registry keys. After that, restart PowerShell and check if the security protocol TLS 1.2 is added. As of last, install the PowerShellGet module.
The first cmdlet is to set strong cryptography on 64 bit .Net Framework (version 4 and above).
[PS] C:\>Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

[PS] C:\>Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
The second cmdlet is to set strong cryptography on 32 bit .Net Framework (version 4 and above).
[PS] C:\>Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

[PS] C:\>Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

Tls, Tls11, Tls12

2
[PS] C:\>[Net.ServicePointManager]::SecurityProtocol
Tls, Tls11, Tls12
Run the command Install-Module PowershellGet -Force and press Y to install NuGet provider, follow with Enter.
[PS] C:\>Install-Module PowershellGet -Force
NuGet provider is required to continue
PowerShellGet requires NuGet provider version '2.8.5.201' or newer to interact with NuGet-based repositories. The NuGet provider must be available in 'C:\Program Files\PackageManagement\ProviderAssemblies' or

Windows 10 Version Update using PowerShell

Am I faced with such a problem that I need to update Widows 10 to next build (for example from 1903 to 1909) using PowerShell.
I use next methods:
1)
$Updates = Start-WUScan
Install-WUUpdates -Updates $Updates
2)
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
Install-Module -Name PSWindowsUpdate -Confirm:$False -Force
Get-Package -Name PSWindowsUpdate
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Unrestricted -Force
$WinUpdates=Get-WindowsUpdate -MicrosoftUpdate -Verbose
Install-WindowsUpdate -KBArticleID $WinUpdates.kb -AcceptAll
Both of these options work great, they find and install updates. BUT! All these updates are for the current build only. Updates to the transition to the next build are not found.
Does anyone know what I'm doing wrong or how to install an update that will allow me to upgrade to the next version of Windows?
I found an article about how you can do a feature upgrade with PowerShell:
$dir = 'C:\_Windows_FU\packages'
mkdir $dir
$webClient = New-Object System.Net.WebClient
$url = 'https://go.microsoft.com/fwlink/?LinkID=799445'
$file = "$($dir)\Win10Upgrade.exe"
$webClient.DownloadFile($url,$file)
Start-Process -FilePath $file -ArgumentList '/quietinstall /skipeula /auto upgrade /copylogs $dir'
I couldn't test it. Here is the source: https://social.technet.microsoft.com/Forums/en-US/51104081-4ed7-4fdd-8b12-5d1f5be532ae/windows-10-feature-update-via-cmd-powershell-or-gpo?forum=win10itprogeneral
using this manual I was able to update the test computer tutorial to get list of windows updates:
Add-WUServiceManager -ServiceID "7971f918-a847-4430-9279-4a52d1efe18d" -AddServiceFlag 7
Get-WUlist -MicrosoftUpdate
But remember in list can be wrong size of updates....
Notice that when installing a build upgrade with PSWindowsUpdate, restart does not yet finalize upgrade. When you have restarted from PowerShell after PSWindowsUpdate has downloaded and installed build upgrade, it is in fact only initialized, not installed.
You must restart once more from Start > Power > Update and restart

Warning while install-module PowerShellGet

While installing PowerShellGet, I perform the following:
Install-PackageProvider Nuget –force –verbose
then I Exit, try running the following:
Install-Module –Name PowerShellGet –Force –Verbose
When I do this, I get the error:
This error occurs when I try to install other modules too, like MSOnline, Azure etc.
I have the latest version of Powershell and also the necessary modules.
I feel that the reason is due to the PowershellGet file.
Is there a way to resolve this issue?
You need to register the PowerShell repository before installing PowerShellGet. Try this
Register-PSRepository -Name “PSGallery” -SourceLocation “https://www.powershellgallery.com/api/v2/" -InstallationPolicy Trusted

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?

I'm trying to install pswindowsupdate.2.0.0.4.nupkg from the Powershell command line on a Win 7 computer not connected to the internet. I'm running PS 5.1.14409.1005. I obtained the nupkg from https://www.preview.powershellgallery.com/packages/PSWindowsUpdate/2.0.0.4
The PS command Install-Module -Name pswindowsupdate.2.0.0.4.nupkg -Repository {path to pswindowsupdate.2.0.0.4.nupkg} throws an error message:
PowerShellGet requires NuGet provider version '2.8.5.201' or newer to interact with NuGet-based repositories. The NuGet provider must be available in 'C:\Program Files\PackageManagement\ProviderAssemblies' or 'C:\Users{my login}\AppData\Local\PackageManagement\ProviderAssemblies'. You can also install the NuGet provider by running 'Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force'. Do you want PowerShell to install and import the NuGet provider now?
Saying 'yes', of course, fails to install the NuGet provider because I'm not connected to the internet.
I obtained nuget.exe (v4.7.0), stored it in 'C:\Program Files\PackageManagement\ProviderAssemblies' and added 'C:\Program Files\PackageManagement\ProviderAssemblies' to my path statement. However, executing Install-Module -Name pswindowsupdate.2.0.0.4.nupkg -Repository {path to pswindowsupdate.2.0.0.4.nupkg} still fails.
What exactly is a NuGet provider? Is it just nuget.exe? How do I obtain and install the Nuget provider (v2.8.5.201 or greater) for PowerShell so I can install this nuget package from the PowerShell command line?
Note: Visual Studio is not in any way involved with my question
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 pswindowsupdate 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

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:
Run Install-PackageProvider -Name NuGet -RequiredVersion 2.8.5.201 -Force to install the provider from a computer with an internet connection.
After the install, you can find the provider installed in $env:ProgramFiles\PackageManagement\ReferenceAssemblies\\\<ProviderName\>\\\<ProviderVersion\>
or
$env:LOCALAPPDATA\PackageManagement\ProviderAssemblies\\\<ProviderName\>\\\<ProviderVersion\>.
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.
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.
Try this:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Install-PackageProvider NuGet -Force
Set-PSRepository PSGallery -InstallationPolicy Trusted
The provider is bundled with PowerShell>=6.0.
If all you need is a way to install a package from a file, just grab the .msi installer for the latest version from the github releases page, copy it over to the machine, install it and use it.
Here is the script I use in a Dockerfile based on windows/servercore to achieve complete PowerShellGallery setup through Artifactory mirrors (also for onegetcdn.azureedge.net)
ARG ONEGET_NUGET_PROVIDER="Microsoft.PackageManagement.NuGetProvider-2.8.5.208.dll"
ARG ONEGET_PROVIDERS="https://artifactory/artifactory/generic-azureedge-onegetcdn/providers/"
RUN $ProviderPath = 'C:/Program Files/PackageManagement/ProviderAssemblies/'; `
New-Item -ItemType "directory" -Path $ProviderPath -Force; `
Invoke-WebRequest -Uri "${Env:ONEGET_PROVIDERS}${Env:ONEGET_NUGET_PROVIDER}" -OutFile "${ProviderPath}${Env:ONEGET_NUGET_PROVIDER}"; `
Register-PSRepository -Name "artifactory-powershellgallery-remote" -SourceLocation "https://artifactory/artifactory/api/nuget/powershellgallery-remote"; `
Unregister-PSRepository -Name PSGallery;
Location and dll version are visible at https://onegetcdn.azureedge.net/providers/providers.masterList.feed.swidtag
None of the options in this thread worked for me. I'm using PowerShell Core 7.1.5. What worked for me was to remove Windows Powershell Modules from $env:PSModulePath. Essentially, check your environment variables and look for any path that has "WindowsPowerShell" and remove it.
In order to install the Nuget Package Manager non-interactively, simply use the -Force flag which bypasses prompting:
Install-PackageProvider NuGet -Force
You do not have to use the trick about the security protocol, at least for Windows Powershell (5.1).

PowerShell package source confirmation

I'm trying to create a function that will automatically install, update and import on demand a PowerShell module from repository PSGallery and this will be run on a build server so I have to avoid any kind of confirmation prompts. This function will be called quite often and will not try to install or update modules if the module is already loaded to the session (only the first time).
# Already imported? Let's not go further with updates and import again...
if (Get-Module -Name $moduleName)
{
Write-Host "'$moduleName' is already imported to the current session!"
return
}
If the module is not already installed, I will try to install it. The problem is when I get to the step that I have to install the NuGet PackageManagement provider (before importing PowerShellGet module needed to install modules from PSGallery). I do the following cmdlet:
Install-PackageProvider -Name "NuGet" -Confirm:$false -Verbose
But I get the following confirmation prompt:
I could solve this issue by using the -Force parameter like that:
Install-PackageProvider -Name "NuGet" -Confirm:$false -Force -Verbose
But the problem I see with that solution (might not be a big deal) is that using -Force will download and install again NuGet every time even if the installed version is up to date. Without the -Force parameter, it will just skip it if the version is up to date and I would much rather that.
Is there a way to set the package source 'https://oneget.org/nuget-2.8.5.208.package.swidtag' as trusted so I don't get the confirmation prompt again without having to use -Force parameter?
Actually, if you run Get-PackageProvider -Name "NuGet" -Force it will automatically download and install it if its not installed. If it is installed, it returns NuGet as an object. My PowerShell version is 5.1.14393.1480.
Original Response:
Maybe you could just check to see if its available and then run your command?
$NuGetProvider = Get-PackageProvider -Name "NuGet" -ErrorAction SilentlyContinue
if ( -not $NugetProvider )
{
Install-PackageProvider -Name "NuGet" -Confirm:$false -Force -Verbose
}
Not sure if this will help, but here goes nothing:
Can you use the cmd version of try-catch using errorlevel?
Install-PackageProvider -Name "NuGet" -Confirm:$false -Verbose
if errorlevel 1 GOTO Forced
exit /b
:Forced
Install-PackageProvider -Name "NuGet" -Confirm:$false -Force -Verbose
How about using the -ForceBoostrap parameter on Get-PackageProvider, e.g.
Get-PackageProvider -Name "nuget" -ForceBootstrap
