Install NuGet via PowerShell script

Question

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.

Answer 1

1. Run Powershell with Admin rights
2. Type the below PowerShell security protocol command for TLS12:

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

Answer 2

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.

Answer 3

This also seems to do it. PS Example:

Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force

Answer 4

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.

Answer 5

使用 PowerShell 但无需创建脚本：

Invoke-WebRequest https://dist.nuget.org/win-x86-commandline/latest/nuget.exe -OutFile Nuget.exe

Answer 6

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
1
[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
1
[PS] C:\>Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
Restart Powershell and check for supported security protocols.

[PS] C:\>[Net.ServicePointManager]::SecurityProtocol
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
'C:\Users\administrator.EXOIP\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 PowerShellGet to install
and import the NuGet provider now?
