I am following the AWS CLI Setup guide. I have managed to successfully install the tool on my Mac OS X terminal with the following output:
Running cmd: /usr/bin/
Here are the three steps to install AWS cli on mac OSX (curl or wget) The third step will set you path correctly
$ curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"
$ unzip awscli-bundle.zip
$ sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws
The other easiest way is to do using homebrew
brew install awscli
If you want the development version you can do
brew install awscli --HEAD
