Setting up pipenv in python project and virtualenv

I am trying to setup python and pip in a new project using virtualenv on mac OS X.

Version details:

> python --version

Python 2.7.10

> pip --version

Running: python -m pip --version

pip 19.2.3 from /Library/Python/2.7/site-packages/pip (python 2.7)

The issue is when I try to set up pip in under the project structure I am seeing an error.
     "no such option: --python"

If I run the command that IntelliJ says it is running on the cli I see the same error.

>pip --python /usr/bin/python2.7 install --dev

Usage:   

  pip <command> [options]

no such option: --python

Looking at the pip usage there appears to be no --python option.
