我正在尝试将教义安装到我的项目中。我收到有关错误的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。

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

作曲家.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",
在你composer.json的某个地方你有
"config": {
"preferred-install": "dist",
"platform": {
"php": "5.3.9"
}
}
该块将覆盖您当前的 PHP 版本，如作曲家文档中所述。
在 composer.json 中，删除以下行：
// ...
"config": {
"platform": {
"php": "5.3.9"
}
},
// ...
请参阅作曲器中的平台配置。
我刚刚遇到了同样的问题（在做" composer install "时）。
但是更改配置不是一种选择（由于办公室的存储库冲突），因此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"
}
}
}
哪个作曲家可以在
composer.lock文件中缓存，例如：{ ... "platform-overrides": { "php": "5.5" } }
但我们也可以忽略它，例如：
composer install --ignore-platform-reqs
我在Symfony 2.7中使用教义迁移
在我的 composer.json 中，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，您可以在此处阅读。
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"
},
我在使用 laravel 7.4 时遇到了这个问题，但我之前使用的是 Laravel 8.2。所以，我不得不从composer.json中删除这些行。谢谢查拉斯。现在它又工作正常了。
