Error when running the required MigrationPrerequisites.ps1

Question

I have installed the latest Az CLI package so I know that's not the issue. But when I run the script locally in Powershell, I can't get past this error: Write-Telemetry : Unhandled exception The term 'Invoke-AzRestMethod' is not recognized as the name of a cmdlet,

function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the

path is correct and try again..
