PHP版本：PHP 5.6.18

PHP 5.6.18  (cli) (built: Feb  3 2016 17:20:21)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0,Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.6-dev,Copyright (c) 1999-2016,by Zend Technologies

错误：c ..> composer需要doctrine / data-fixtures

Using version ^1.1 for doctrine/data-fixtures
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  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
8) overriden by "config.platform.php" version (5.3.9) does not satisfy that requ
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
8) overriden by "config.platform.php" version (5.3.9) does not satisfy that requ
irement.
    - doctrine/migrations v1.1.0 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 v1.0.0 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.
    - Installation request for doctrine/migrations ~1.0 -> satisfiable by doctri
ne/migrations[v1.0.0,v1.1.0,v1.2.0,v1.2.1,v1.2.2,v1.3.0].


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

composer.json的内容

"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",

你的composer.json的某个地方

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

该块将覆盖您当前的PHP版本,如composer doc所述.
