If you are using Publish-Module to publish your modules to a PowerShell repository, and you keep getting exceptions about unsupported commands, it might be worthwhile to reinstall the executables that manage the module upload. When these executables get too old, they may no longer be in sync with the latest PowerShellGet module.

Run this to download and update nuget.exe with Administrator privileges (for all users):

$Path = "$env:ProgramData\Microsoft\Windows\PowerShell\PowerShellGet"
$exists = Test-Path -Path $Path
if (!$exists)
{
    $null = New-Item -Path $Path -ItemType Directory 
}
Invoke-WebRequest -Uri https://aka.ms/psget-nugetexe -OutFile "$Path\NuGet.exe"

Run this to download and install nuget.exe for your current user only:

$Path = "$env:LOCALAPPDATA\Microsoft\Windows\PowerShell\PowerShellGet"
$exists = Test-Path -Path $Path
if (!$exists)
{
    $null = New-Item -Path $Path -ItemType Directory 
}
Invoke-WebRequest -Uri https://aka.ms/psget-nugetexe -OutFile "$Path\NuGet.exe"
