Failed to add PATH for pipenv error on WIN10

Hello, I am trying to add PATH for pipenv, cause I got error:
pipenv : The term ‘pipenv’ is not recognized as the name of a cmdlet…

I successfully installed pipenv, I got warning that i may get error because my path is not good.
I tried many things to resolve this problem, but nothing worked.
I tried this:
setx PATH “%PATH%;C:\Users\G4G\AppData\Roaming\Python\Python39\Scripts”
Also i tried to install pipenv with pip --user install pipenv, I did this: “First, remove your current version of virtualenv”. And I am still getting error. Some tip?
