Pipenv environement is still working with Python 3.6.5 even if 3.7.0 is specified.

To upgrade your pipenv you have to install Python 3.7 with pyenv pyenv install 3.7.0 and then pipenv --python 3.7 to use this version, and pipenv install to install dependencies.

I don’t know why pipenv is depending on pyenv for Python version.
