using pipenv with git submodules
go to the directory where each pipfile exist and run pipenv install. Make sure your virtualenv is activated.
I have a git submodule B, that works as an app in my django project A. B has its own Pipfile and Pifile.lock. A also has a Pipfile and Pipfile.lock. How can I use pipenv, to install the libraries  from both pipfiles within the same virtuaelenv?
