Symfony2、composer、 "config.platform.php"バージョン（5.3.9）でオーバーライドされたPHPバージョン（5.6.18）は、php、symfony、doctrine2、composer-php

私は自分のプロジェクトに教義をインストールしようとしています。 間違ったPHPバージョンに関するエラーが表示されます。このエラーの本当の理由を取り除くために何ができますか？それを克服する方法は、オプション「--ignore-platform-reqs「説明どおり https://getcomposer.org/doc/03-cli.md#require .

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].

あなたのどこかに composer.json あなたが持っている

"config": {
"preferred-install": "dist",
"platform": {

}
}
