Slim + Twig - 如何在开发过程中关闭 Twig 缓存?

This is the view which is twig that I inject it in the container in Slim:

// Views and Templates
// https://www.slimframework.com/docs/features/templates.html
$container['view'] = function ($container) {
    $settings = $container->get('settings');

    $loader = new Twig_Loader_Filesystem('templates');
    $twig = new Twig_Environment($loader, array(
        'cache' => 'cache',
    ));

    // Add twig extension.
    $twig->addExtension(new Twig_Extensions_Extension_Array());
    return $twig;
};

使用此设置，Twig 总是从缓存中读取模板.在开发过程中有什么办法可以关闭缓存?

$twig = new Twig_Environment($loader, array(
    'cache' => false,
));
