Symfony2, Composer, Ihre PHP-Version (5.6.18) überschrieben durch "config.platform.php" Version (5.3.9) erfüllt nicht die Anforderung

Question

Ich versuche, Doktrin zu meinem Projekt zu installieren. Ich bekomme den Fehler über die falsche PHP-Version. Was kann getan werden, um den wahren Grund für diesen Fehler zu entfernen? Der Weg, dies zu überwinden, ist die Verwendung der Option "--ignore-platform-reqs" wie beschrieben https://getcomposer.org/doc/03-cli.md#require.

PHP-Version: PHP 5.6.18

    Problem 1 
    - doctrine/migrations v1.3.0 requires php ^5.5|^7.0 -> your PHP version (5.6

Installation failed, reverting ./composer.json to its original content. 

Der Gehalt an composer.json

"require": { 
    "php": ">=5.3.9", 
    "symfony/symfony": "2.8.*", 
    "doctrine/orm": "^2.4.8", 
    "doctrine/doctrine-bundle": "~1.4", 
    "doctrine/data-fixtures" : "~1.1", 
    "doctrine/doctrine-fixtures-bundle": "dev-master", 

Answer 1

Entfernen Sie in Ihrem composer.json die folgenden Zeilen:

// ... 
"config": { 
    "platform": { 
     "php": "5.3.9" 
    } 
}, 
// ... 

Siehe platform config in composer.

Answer 2

Irgendwo in Ihrem composer.json Sie haben

"config": { 
    "preferred-install": "dist", 
    "platform": { 
     "php": "5.3.9" 
    } 
} 

Dieser Block Ihre aktuelle PHP-Version überschreibt, wie in composer doc beschrieben.

Answer 3

verwende ich Lehre Migrationen mit Symfony 2.7

In meinem composer.json ich habe, ich bemerkt, dass Sie dies nicht tun, Sie mit dem Hinzufügen es folgende Symfony2 docs

"doctrine/doctrine-migrations-bundle": "^1.0" 

ich manuell installiert Migrationen könnten versuchen, Sie können es lesen here.

Das ist mein ganzer 2,7 Symfony Komponist:
