The following is a list of operating system-level tools that Acquia BLT uses.
Not all of these are absolutely required. Some are required only when using certain features of Acquia BLT, such as Selenium-based testing or Drupal VM integration.
For installation instructions, see Installing Acquia BLT.
Tool | Required | Purpose |
---|---|---|
PHP | Yes | Required by several tools, including Composer, Drush, Robo, and Drupal. Ensure the following recommendations are met:
|
Composer | Yes | Used to manage project-level dependencies for Acquia BLT and Drupal.
Composer is the default package manager for the PHP community, and
is also used by Drupal core. For information about using Composer in conjunction with Acquia BLT, see Using Composer to manage dependencies. You can update to the latest version of Composer by using the following command: composer self-update |
Git | Yes | A distributed version control system. It is the VCS tool for the Drupal community. |
Drush | Yes | Command line shell and Unix scripting interface for Drupal. Acquia BLT
uses Drush to communicate with Drupal from the command line. Drush is both a system level and a project level dependency, which is unusual. It is possible to have one version of Drush on your computer and a different version of Drush used in your project directory. This is useful but frequently causes confusion. Drush uses a special launcher script to look for a copy of Drush that is specific to your project. BLT ships such project-level drush binary in the vendor/bin directory of your project. Your global Drush
installation defers to the project level binary when executing
drush from an Acquia BLT project directory. |
Java | No | Required by Selenium to communicate with Chrome. Selenium is one option for executing JavaScript Behat tests. For more information, see Automated testing. |
ChromeDriver | No | Required by Selenium to communicate with Chrome. Selenium is one option for executing JavaScript Behat tests. For more information, see Automated testing. |
Ansible | No | Required by Drupal VM, which is one option for local development. |
Vagrant | No | Required by Drupal VM, which is one option for local development. |
VirtualBox | No | Required by Drupal VM, which is one option for local development. |
Yarn | No | A package manager for JavaScript. |
nvm | No | Manages multiple versions of NodeJS on a single computer. |

.Headless Chrome is used by default for Behat tests, although you can also use Selenium or PhantomJS.
Note for Docker users
Connections to Headless Chrome will occasionally time out in containerized environments, such as Docker. For discussion and a possible solution, see this issue on GitHub.
