使用php 5.5.9的作曲家无法安装Laravel 5.2

Question

I'm trying to set up a Laravel project on the server with php 5.5.9.

I've specially remembered to use Laravel 5.2 and only packages that support php 5.5, but I'm still getting errors, although Laravel itself says everything should be fine:

Any idea why is this doctrine/annotations suddenly asking for php 5.6?

Edit: This is my current composer.json file:

"require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.2.*",
    "guzzlehttp/guzzle": "^6.2"
},
"require-dev": {
    "fzaninotto/faker": "~1.4",
    "mockery/mockery": "0.9.*",
    "phpunit/phpunit": "~4.0",
    "symfony/css-selector": "2.8.*|3.0.*",
    "symfony/dom-crawler": "2.8.*|3.0.*"
},

Run composer update first and then install laravel. I think this guy explains it very well copmposer update vs composer install
