{} is not resolvable

[NassimaZIANI]

I am trying to add caching to Slim 3, I followed the instruction in https://www.slimframework.com/docs/v3/features/caching.html :

$app = new Slim\App(['settings' => $config]);
$container = $app->getContainer();
$container['cache'] = function () {
    return new \Slim\HttpCache\CacheProvider();
};
$app->add(new \Slim\HttpCache\Cache('public', 86400));

but I get the following error :
