# Installing, updating, and uninstalling the Amazon CLI
<a name="cli-chap-install"></a>

This topic provides links to install, update, and uninstall the original version of the Amazon Command Line Interface (Amazon CLI). The Amazon CLI version 1 is currently supported, but new features added to the Amazon CLI version 2 might not be added to the Amazon CLI version 1. To use those features, you must install the Amazon CLI version 2. For information about how to install version 2, see [Installing the Amazon CLI version 2](https://docs.amazonaws.cn/cli/latest/userguide/cli-chap-getting-started.html).

## Python version requirements

The Amazon CLI version 1 is built using the SDK for Python, and therefore requires you to install a compatible version of Python.
