My server is using PHP version 5, therefore, I need to install Drupal 8 version 8.6.18. But when I try,
composer create-project drupal-composer/drupal-project:8.x-dev my_site_name_dir --no-interaction --no-install, I get the following error.
[InvalidArgumentException] Could not find package drupal-composer/drupal-project with version 8.x-dev in a version installable using your PHP version 5.6.40.
Is there anyway to install 8.6.18 with composer?
