Pipenv command not found?

Learn Python: Pipenv

so i installed python 3 and pip on my mac after that i followed through the instructions however when i type
pipenv --version

on terminal i get the error:
command not found: pipenv

everyting worked up until this point how can i fix this?

I’m having the same problem. Did you find a solution? When I go to add the PATH there is already one there and I don’t know where/how to add in this one.
