Невозможно запустить Powershell Command

Question

Это мой первый набег в Powershell. Когда я запускаю скрипт Powershell, я получаю следующее сообщение об ошибке:

PS D:\modules\setup-azure> Setup-Azure
Setup-Azure : The term 'Setup-Azure' 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.

+ ~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Setup-Azure:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

PS D:\modules\setup-azure> Setup-Azure.psm
Setup-Azure.psm : The term 'Setup-Azure.psm' 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.

PS D:\modules\setup-azure>

Может кто-нибудь, пожалуйста, пролить свет на сообщение об ошибке?
