Issue Description

I suspect you are aware of this. This is for other users who may have this issue.

The following is displayed in the terminal:

WARNING: Failed to import Pester version 5.0.0. You must install Pester module to run or debug Pester tests.
WARNING: You can install Pester by executing: Install-Module Pester -MinimumVersion 5.0.0 -Scope CurrentUser -Force

Executing Install-Module Pester -MinimumVersion 5.0.0 -Scope CurrentUser -Force results in the following error:

> Install-Module Pester -MinimumVersion 5.0.0 -Scope CurrentUser -Force

Install-Package: C:\program files\powershell\7\Modules\PowerShellGet\PSModule.psm1:9685:34

Expected Behaviour

I expected Pester 5 to be installed.

Actual Behaviour

I got an error.

Workaround:

> Install-Module Pester -Scope CurrentUser -Force -AllowPrerelease

> get-module pester -ListAvailable | ? Version -eq '5.0.0'

Pester 5 is still in beta so you have to use -AllowPrerelease

This is by-design. Unless I'm missing something here, we can close this as such?

PowerShellGet is getting a massive overhaul so you may want to be involved in that RFC:

PowerShell/PowerShell-RFC#237

@TylerLeonhardt Sure, I'll close this issue.

Thanks @mrboring! Do follow that RFC and give us your feedback
