I was trying to install Azure using Install-Module Azure in PowerShell. I got the following error:

Answer 1

I didn't have the NuGet Package Provider, you can check running Get-PackageProvider:

PS C:\WINDOWS\system32> Get-PackageProvider 

Name                     Version          DynamicOptions                                                                                                                 
----                     -------          --------------                                                                                                                 
msi                      3.0.0.0          AdditionalArguments                                                                                                            
msu                      3.0.0.0                                                                                                                                         
NuGet  <NOW INSTALLED>   2.8.5.208        Destination, ...                             

The solution was installing it by running this command:

Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force

If that fails with the error below you can copy/paste the NuGet folder from another PC (admin needed): C:\Program Files\PackageManagement\ProviderAssemblies\NuGet:

Answer 2

I have Windows 10 and PowerShell 5.1 was already installed. For whatever reason the x86 version works and can find "Install-Module", but the other version cannot.

Search your Start Menu for "powershell", and find the entry that ends in "(x86)":

Here is what I experience between the two different versions:

Answer 3

Actually my solution to this problem was much simpler, because I already had the latest version of PowerShell and is still didn't recognize Install-Module command. What fixed the "issue" for me was just typing the command manually, since originally I tried copying the snippet from a website and apparently there was some issue with the formatting when copy&pasting, so when I typed the command manually it installed the module without any problem.

Answer 4

I think the above answer posted by Jeremy Thompson is the correct one, but I don't have enough street cred to comment. Once I updated nuget and powershellget, Install-Module was available for me.

Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force 
Install-PackageProvider -Name Powershellget -Force

What is interesting is that the version numbers returned by get-packageprovider didn't change after the update.
