Installing the AWS CLI

The AWS Command Line Interface is available in two versions.

AWS CLI version 2

AWS CLI version 2 is the most recent major version of the AWS CLI and supports all of the latest features. Some features introduced in version 2 are not backward compatible with version 1 and you must upgrade to access those features.

AWS CLI version 2 is available to install only as a bundled installer. Although you might find it in some package managers, these are not produced or managed by AWS and are therefore not official and not supported by AWS. We recommend that you install the AWS CLI from only the official AWS distribution points, as documented in this guide.

For information about how to install AWS CLI version 2, see Installing the AWS CLI version 2.

AWS CLI version 1

AWS CLI version 1 is the original AWS CLI, and we continue to support it. However, major new features that are introduced in AWS CLI version 2 might not be backported to AWS CLI version 1. To use those features, you must install AWS CLI version 2.

For information about how to install AWS CLI version 1, see Installing the AWS CLI version 1.

Migrating from AWS CLI version 1 to version 2

If you ran commands or scripts with AWS CLI version 1 and you are considering migrating to AWS CLI version 2, see Breaking Changes – Migrating from AWS CLI version 1 to version 2 for a description of the changes that you should know about.
