How to uninstall aws-cli

I had a similar issue. Answering in case someone else does too. I think I had originally installed it without pip like this: https://docs.aws.amazon.com/cli/latest/userguide/awscli-install-bundle.html. So you just need to uninstall it like this (as instructed in above link):

$ sudo rm -rf /usr/local/aws
$ sudo rm /usr/local/bin/aws

Then you can re-install it with pip3: https://docs.aws.amazon.com/cli/latest/userguide/cli-install-macos.html

Basically:

pip3 install awscli --upgrade --user

Then add it to your path

export PATH=/Users/yourname/Library/Python/3.6/bin/:$PATH

On ubuntu :

sudo apt-get remove --auto-remove awscli

ln -s /home/ubuntu/.local/bin/aws /usr/bin/aws
