Symfony2,作曲家,您的PHP版本(5.6.18)覆盖"config.platform.php"版本(5.3.9)不符合要求

Question

我正在尝试将doctrine安装到我的项目中.我收到错误的PHP版本的错误.可以采取哪些措施来消除此错误的真正原因？克服它的方法是使用https://getcomposer.org/doc/03-cli.md#require所述的选项" --ignore-platform-reqs" .

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-fixture

Using version ^1.1 for doctrine/data-fixtures
./composer.json has been updated
Loading composer repositories with package information

  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",

Answer 1

在某处,composer.json你有

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

该块会覆盖当前的PHP版本,如composer doc中所述.

Answer 2

在您的composer.json中,删除以下行:

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

请参阅composer中的platform config.
