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/
I have used Homebrew to install AWS CLI and I am quite happy with the result. Simply type:
$ brew install awscli
after you have installed brew.
Note, on the AWS CLI installation page there is the following disclaimer:
The awscli package may be available in repositories for other package managers such as APT, yum and Homebrew, but it is not guaranteed to be the latest version.
That said, I have not found this to be a problem, the awscli.rb has been updated quite frequently to match the latest releases.
Update: there is a GitHub issue that suggests that Homebrew should be added as an alternative in the AWS CLI installation instructions. This issue was later closed in favor of this UserVoice feature request.
