Symfony2，作曲家，您的 PHP 版本（5.6.18）被“config.platform.php”版本（5.3.9）覆盖不满足要求

Question

我正在尝试将教义安装到我的项目中。我收到有关错误 PHP 版本的错误。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。

PHP 版本：PHP 5.6.18

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

    - 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

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

在你的composer.json 中的某个地方

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

该块会覆盖您当前的 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"
    }
},
// ...

见platform config in composer。

我在 Symfony 2.7 中使用学说迁移

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"

我按照 Symfony2 文档手动安装了迁移，您可以阅读它here。

这是我的整个 2.7 Symfony 作曲家：

"require": {
    "php": ">=5.3.9",
    "symfony/symfony": "2.7.*",
    "doctrine/orm": "~2.2,>=2.2.3,<2.5",
    "doctrine/dbal": "<2.5",
    "doctrine/doctrine-bundle": "~1.4",
    "symfony/assetic-bundle": "~2.3",
    "symfony/swiftmailer-bundle": "~2.3",
    "symfony/monolog-bundle": "~2.4",
    "sensio/distribution-bundle": "~4.0",
    "sensio/framework-extra-bundle": "~3.0,>=3.0.2",
    "incenteev/composer-parameter-handler": "~2.0",
    "friendsofsymfony/user-bundle": "1.3.*@dev",
    "ircmaxell/password-compat": "^1.0",

    "sonata-project/block-bundle": "2.3.*@dev",
    "sonata-project/easy-extends-bundle": "^2.1",
    "sonata-project/datagrid-bundle": "~2.2@dev",
    "sonata-project/admin-bundle": "~2.3@dev",
    "sonata-project/doctrine-orm-admin-bundle": "~2.3@dev",
    "sonata-project/user-bundle": "~2.3@dev",
    "doctrine/doctrine-migrations-bundle": "^1.0"

},

我刚刚遇到了同样的问题（在执行“composer install”时）。

但是更改配置不是一个选项（因为 office 的 repo 冲突），所以我想出了以下解决方案。

全局配置文件^{（或忽略PHP版本）}

建议只伪造和/或配置 “~/.composer/config.json”文件（或 Windows 的“%AppData%/Composer/config.json”文件）中的 PHP 版本，如：

{
    "config": {
        "platform":{
            "php":"5.5"
        }
    }
}

哪个作曲家可以缓存在composer.lock文件中，比如：

{

   ...

   "platform-overrides": {
       "php": "5.5"
   }
}

但我们也可以忽略它，例如：

composer install --ignore-platform-reqs
