install_display_requirements($install_state, $requirements)
Displays installation requirements.
Parameters
array $install_state: An array of information about the current installation state.
array $requirements: An array of requirements, in the same format as is returned by hook_requirements().
Return value
A themed status report, or an exception if there are requirement errors. If there are only requirement warnings, a themed status report is shown initially, but the user is allowed to bypass it by providing 'continue=1' in the URL. Otherwise, no output is returned, so that the next task can be run in the same page request.
Throws
\Drupal\Core\Installer\Exception\InstallerException
