Symfony项目显示目录索引而不是索引页

Question

I am new to Symfony, and I've just created a new project on a Debian server. The folder is /var/www/symfony. I've use the instructions as defined here: https://symfony.com/doc/current/book/installation.html

When I access that folder from my web browser, I see the directory index with files. But I'm missing the default page.

I've checked the following:

1. Permissions have been configured as read/write for the web server user/group/
2. The Directory in Apache2 has been configured as AllowOverrride All
3. The DefaultController.php file has a "/" route defined.

When I try to run the PHP internal web server from the project directory (php bin/console server:run):

PHP Parse error:  syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in /var/www/symfony/vendor/symfony/symfony/src/Symfony/Component/Debug/ErrorHandler.php on line 386
PHP Stack trace:
PHP   1. {main}() /var/www/symfony/bin/console:0
PHP   2. Symfony\Component\Debug\Debug::enable() /var/www/symfony/bin/console:24
PHP   3. Composer\Autoload\ClassLoader->loadClass() /var/www/symfony/bin/console:0
PHP   4. Composer\Autoload\includeFile() /var/www/symfony/vendor/composer/ClassLoader.php:301

I'm running PHP 5.4.54. Is this a bug in Symfony, or am I missing something?

Symfony 3.0 and above requires you to use PHP 5.5.9 or higher.
