public function ModuleInstallerInterface::install

Installs a given list of modules.

Order of events:

• Gather and add module dependencies to $module_list (if applicable).
• For each module that is being installed:
  • Invoke hook_module_preinstall().
  • Install module schema and update system registries and caches.
  • Invoke hook_install() and add it to the list of installed modules.
• Invoke hook_modules_installed().

To install test modules add

$settings['extension_discovery_scan_tests'] = TRUE;

to your settings.php.

Parameters

string[] $module_list: An array of module names.

bool $enable_dependencies: (optional) If TRUE, dependencies will automatically be installed in the correct order. This incurs a significant performance cost, so use FALSE if you know $module_list is already complete.

Return value

bool TRUE if the modules were successfully installed.

Throws

\Drupal\Core\Extension\MissingDependencyException Thrown when a requested module, or a dependency of one, can not be found.

\Drupal\Core\Extension\ExtensionNameLengthException Thrown when the extension's name is longer than DRUPAL_EXTENSION_NAME_MAX_LENGTH.

\Drupal\Core\Extension\ExtensionNameReservedException Thrown when a module's name is already used by an installed theme.
