Answer 1

Try pip3 install. It happens when I'm on my MacBook.

Answer 2

Try this instead:

Add the scripts folder to PATH

C:\\Users....\\AppData\\Local\\Programs\\Python\\Python39\\Scripts

or

C:\\Python39\\Scripts (depending on how you have installed python locate and add python/scripts folder)
