The array of compound arrays autoload_namespaces is empty, but it loads my packages

Question

I use composer in windows and it successfully loads my 2 packages, which I use from my composer.json file when I execute composer installor composer update.

{
    "require": {
        "bcosca/fatfree": "dev-master",
        "respect/validation": "^1.1"
    }
}

First line in my index.php

require_once __DIR__ . '\vendor\autoload.php';

It seems that nothing was loading, for example, there were a lot of errors related to classes not defined from these 2 packages. I looked through it further and found that mine autoload_namespaces.phplooked like this:

<?php

// autoload_namespaces.php @generated by Composer

$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);

return array(
);

The array is completely empty, how does this happen? I expected to see these requirements for two packages here ...

Thanks for the help!

Adding the .json composer from the packages themselves: F3:
