When you try to install a python project using pip and you are using macOS and you get the error:
Installing collected packages: six, python-dateutil, docutils, botocore, pyasn1, rsa, colorama, awscli Found existing installation: six 1.4.1 DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

MacOS ships with six 1.4.1 installed already and when it attempts to uninstall it doesn't have permission to do so because System Integrity Protection doesn't allow even root to modify those directories. Try to install the six using the command:
pip install --ignore-installed six
