在 Symfony 4/5 中安装 orm-fixtures 时 Composer 发生冲突

Question

当我尝试orm-fixtures在 Symfony 5.1 中安装时遇到问题：

$ composer require orm-fixtures --dev
Using version ^3.3 for doctrine/doctrine-fixtures-bundle
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Restricting packages listed in "symfony/symfony" to "5.1.*"
Your requirements could not be resolved to an installable set of packages.

Installation failed, reverting ./composer.json to its original content.

这是我得到的错误。

我知道这个问题来自我的库版本，但我不知道如何解决它我今天才启动 Symfony。

Answer 1

更新：确认截至 2020 年 9 月 1 日，问题已解决。固定装置现在可以干净地加载，无需任何调整。那些使用过这个程序的人可能想要从冲突部分中删除教义行，然后再做一次 Composer 更新，只是为了恢复同步。

要重现该问题，请从一个新的 5.1 项目开始并尝试安装设备包：

symfony new --full new_project
cd new_project
composer require --dev orm-fixtures

你会收到很长很长的错误信息。这是权力正在努力的事情。实际上，这种问题在各种测试过程中都被忽略了，这有点奇怪。非常稀有。

但是，您可以通过进行一些教义降级来解决它。将这些原则行添加到 composer.json：

    "conflict": {
        "symfony/symfony": "*",
        "doctrine/common": ">= 3.0",
        "doctrine/persistence": "<1.3"
    },

然后，秘密成分，您应该清除作曲家缓存并进行作曲家更新以实际降级教义：

composer clear-cache
composer update
composer require --dev orm-fixtures

它应该工作。

但同样，这一切都有望在不久的将来得到解决。
