Symfony2, compositore, la versione PHP (5.6.18) sostituita dalla versione "config.platform.php" (5.3.9) non soddisfa il requisito

Question

Sto provando ad installare doctrine nel mio progetto. Sto ottenendo l'errore sulla versione PHP sbagliata. Cosa si può fare per rimuovere la vera ragione di questo errore? Il modo per superarlo è usare l'opzione "--ignore-platform-reqs" come descritto https://getcomposer.org/doc/03-cli.md#require.

PHP versione: PHP 5.6.18

PHP 5.6.18 (cli) (built: Feb 3 2016 17:20:21)

L'errore: c ..> compositore richiedere doctrine/dati-infissi

    Problem 1 
    - doctrine/migrations v1.3.0 requires php ^5.5|^7.0 -> your PHP version (5.6 
.18) overriden by "config.platform.php" version (5.3.9) does not satisfy that re 
quirement. 
    - doctrine/migrations v1.2.2 requires php >=5.4.0 -> your PHP version (5.6.1

irement. 
    - doctrine/migrations v1.2.1 requires php >=5.4.0 -> your PHP version (5.6.1 
8) overriden by "config.platform.php" version (5.3.9) does not satisfy that requ 
irement. 
    - doctrine/migrations v1.2.0 requires php >=5.4.0 -> your PHP version (5.6.1

irement. 
    - doctrine/migrations v1.0.0 requires php >=5.4.0 -> your PHP version (5.6.1

irement. 
    - Installation request for doctrine/migrations ~1.0 -> satisfiable by doctri

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

Il contenuto di 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

Nel tuo compositore.json, rimuovere le seguenti righe:

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

Vedere platform config in composer.

Answer 2

qualche parte nel vostro composer.json avete

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

che bloccano prevale la versione di PHP corrente, come descritto nel composer doc.

Answer 3

Io uso migrazioni dottrina con Symfony 2.7
