Requirements
Acquia CLI requires PHP 8.0 or later, with the PHP-JSON and PHP-PHAR extensions enabled. If you use PHP 7.4, follow the instructions to download earlier releases.
Commands that require a Cloud Platform account prompt you to link your account, if necessary. For more information, see Authenticating with Cloud Platform API.
Installing Acquia CLI
Note
Acquia CLI is distributed as a standalone Phar archive. Do not install Acquia CLI using Composer, as it might create dependency conflicts.
After installing Acquia CLI, proceed to Getting started with Acquia CLI.
Installing unstable releases
To enable a larger audience to test new features, Acquia sometimes publishes unstable releases, such as alpha or beta.
Important
Preview releases may contain critical bugs. Use them at your own risk.
To allow Acquia CLI to download unstable releases, run the following command:
$ acli self-update --preview
Downloading Acquia CLI (acquia/cli) 1.30.0-beta1
Download finished
Successfully updated acli
To revert Acquia CLI to download stable releases only, run the following command:
$ acli self-update --stable
Downloading Acquia CLI (acquia/cli) 1.30.0
Download finished
Successfully updated acli
Installing earlier releases
Acquia recommends you to install Acquia CLI 2.x. It is the latest supported version and receives frequent feature updates. Acquia CLI 2.x requires PHP 8. If you use PHP 7, you can install Acquia CLI 1.x, which is minimally supported.
To install Acquia CLI 1.x, follow the earlier steps after replacing the download URL with the latest 1.x release:
curl -OL https://github.com/acquia/cli/releases/download/1.30.1/acli.phar
Note
Acquia does not recommend installing Acquia CLI 1.x.
