AWS CLI not working because of unsupported Python version

while installation, choosing python3 worked well for me. Choose the "To install the AWS CLI version using the bundled installer" from here: https://docs.aws.amazon.com/cli/v1/userguide/install-macos.html

sudo /usr/local/bin/python3 awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws

Replace /usr/local/bin/python3 with the path to your python binary with version >= 3.6.

My problem was that I was trying to download an old version of the awscli. After downloading the newest version I ran into some issues with the credentials file. Upon updating the credentials file and adding a config file in the .aws directory, everything worked as expected.
