Repair PowerShellGet and Publish-Module

by Dec 7, 2021

Publish-Module is a cmdlet used to publish (upload) a module to a NuGet repository. Occasionally, this cmdlet raises strange exceptions. The reason in this case is an outdated version of nuget.exe. This application is responsible for packaging a module and saving it as .nupkg file, and this application is automatically downloaded the first time you use Publish-Module.

To correct this problem and refresh your version of nuget.exe, run this:

Invoke-WebRequest -Uri -OutFile "$env:LOCALAPPDATA\Microsoft\Windows\PowerShell\PowerShellGet\NuGet.exe"

Make sure you close and restart all PowerShell sessions after this. If Publish-Module still refuses to work, you may have to run the command below (which requires Admin privileges):

Install-PackageProvider -Name NuGet -MinimumVersion -Force
