Having issues with dependencies and virtual environments when I run pipenv lock and when I try to install django using this command.

I am basically trying to use this tutorial but I having issues with python 3.6 and 3.7 and the pipenv command in general. Any assistance would help. here is the error info below.

(revdjangoenv) C:\Users\Demayne Collins\Desktop\pages\pages_project>pipenv lock

Warning: Your Pipfile requires python_version 3.6, but you are using 3.7.0 (C:\Users\D\.\p\S\python.exe).

  $ pipenv check will surely fail.

Updated Pipfile.lock (ca72e7)!

Why does pipfile only require python version 3.6?
