PowerShellGet - Why won't it update

Fighting with trying to get the latest version of PowerShellGet on my Windows machine because I wanted to prettify my prompt

You will quickly realize the issue when you try to use an unknown parameter when installing modules i.e. AllowPrerelease

In this case I ran this command Install-Module PSReadLine -AllowPrerelease -Force

PowerShellGet 1.0.0.1 does not have this option or much of anything useful so first try to upgrade it with Update-Module PowerShellGet -Force

Hopefully that worked for you: Check it here Get-Command Install-Module

It did not work for me as it continued to keep PowershellGet 1.0.0.1.  Now do the more direct removal of this troublesome library.

• Browse to C:\Program Files\WindowsPowerShell\Modules\
• Open the folder C:\Program Files\WindowsPowerShell\Modules\PowershellGet and delete the subfolder 1.0.0.1
• Open the folder C:\Program Files\WindowsPowerShell\Modules\PackageManagement and delete the subfolder 1.0.0.1
• Browse to C:\Program Files (x86)\WindowsPowerShell\Modules\
• Open the folder C:\Program Files (x86)\WindowsPowerShell\Modules\PowershellGet and delete the subfolder 1.0.0.1
• Open the folder C:\Program Files (x86)\WindowsPowerShell\Modules\PackageManagement and delete the subfolder 1.0.0.1

Now run Install-Module PowerShellGet -Force and Update-Module PowerShellGet

Check the installation Get-Command Install-Module
