Symfony2, composer, your PHP version (5.6.18) overriden by "config.platform.php" version (5.3.9) does not satisfy requirement

提问by Gintare Statkute

I am trying to install doctrine to my project. I am getting the error about the wrong PHP version. What can be done to remove the real reason for this error? The way to overcome it is to use the option "--ignore-platform-reqs" as described https://getcomposer.org/doc/03-cli.md#require.

我正在尝试将学说安装到我的项目中。我收到有关错误 PHP 版本的错误消息。可以做些什么来消除此错误的真正原因？克服它的方法是使用选项“ --ignore-platform-reqs”，如https://getcomposer.org/doc/03-cli.md#require所述。

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

Somewhere in your composer.jsonyou have

在你的某个地方composer.json你有

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

That block overrides your current PHP version as described in composer doc.

该块将覆盖您当前的 PHP 版本，如composer doc 中所述。

In your composer.json, remove the following lines :

在您的 composer.json 中，删除以下几行：

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

See platform config in composer.

请参阅composer 中的平台配置。

I use doctrine migrations with Symfony 2.7

我在 Symfony 2.7 中使用了学说迁移

In my composer.json I have, I noticed you don't, you could try adding it

在我的 composer.json 我有，我注意到你没有，你可以尝试添加它

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

I manually installed migrations following Symfony2 docs, you can read it here.

我按照 Symfony2 文档手动安装了迁移，您可以在此处阅读。
