在 Symfony 4/5 中安装 orm-fixtures 时发生 Composer 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 --devUsing version ^3.3 for doctrine/doctrine-fixtures-bundle./composer.json has been updatedLoading composer repositories with package informationUpdating 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.  Problem 1    - Conclusion: don't install doctrine/doctrine-fixtures-bundle 3.3.1    - Conclusion: remove doctrine/cache 1.10.2    - Conclusion: don't install doctrine/cache 1.10.2    - doctrine/common 2.2.1 conflicts with doctrine/cache[1.10.2].    - doctrine/common 2.2.2 conflicts with doctrine/cache[1.10.2].    - doctrine/common 2.2.3 conflicts with doctrine/cache[1.10.2].    - doctrine/common 2.3.0 conflicts with doctrine/cache[1.10.2].    - Conclusion: don't install doctrine/common 3.0.2|install doctrine/common 2.2.1|install doctrine/common 2.2.2|install doctrine/common 2.2.3|install doctrine/common 2.3.0    - Conclusion: don't install doctrine/doctrine-fixtures-bundle 3.3.1|remove doctrine/common 3.0.2|install doctrine/common 2.2.1|install doctrine/common 2.2.2|install doctrine/common 2.2.3|install doctrine/common 2.3.0    - Conclusion: don't install doctrine/doctrine-fixtures-bundle 3.3.1|don't install doctrine/common 3.0.2|install doctrine/common 2.2.1|install doctrine/common 2.2.2|install doctrine/common 2.2.3|install doctrine/common 2.3.0    - Installation request for doctrine/cache (locked at 1.10.2) -> satisfiable by doctrine/cache[1.10.2].    - Conclusion: don't install doctrine/doctrine-fixtures-bundle 3.3.1|remove doctrine/common 3.0.2|install doctrine/common 2.2.1|install doctrine/common 2.2.2|in

Answer 1

现在，装置可以干净地加载，无需任何调整。使用此过程的人可能希望从冲突部分中删除条令行，并进行另一个作曲家更新以恢复同步。

要重现该问题，请从新的 5.1 项目开始并尝试安装固定装置包：

symfony new --full new_project

cd new_project

composer require --dev orm-fixtures

然后您会收到又大又长的错误消息。这是当权者正在努力的事情。实际上有点奇怪的是，这类问题竟然在各种测试过程中都被忽略了。很稀少。

然而，你可以通过做一些原则降级来解决这个问题。将这些学说行添加到composer.json：

    "conflict": {

        "symfony/symfony": "*",

        "doctrine/common": ">= 3.0",

        "doctrine/persistence": "<1.3"

    },

然后，秘密成分是，您应该清除作曲家缓存并进行作曲家更新以实际降级学说：

composer clear-cache

composer update

composer require --dev orm-fixtures

它应该有效。

但同样，这有望在不久的将来得到解决。

Answer 2

正如错误消息中所写：最新版本的doctrine/doctrine-fixtures-bundlerequire doctrine/data-fixtures。该软件包尚不与doctrine/commonv3 兼容，但该版本当前已安装在您的系统上。

无论您如何安装doctrine/common，都需要将其降级。如果您需要帮助，请编辑您的问题以包含您的composer.json

Answer 3

正在修复：https://github.com/doctrine/data-fixtures/pull/349/files

同时您可以通过添加来安装它

"repositories": [

    {

        "type": "vcs",

        "url": "https://github.com/fruitwasp/data-fixtures"

    }

],

到你的composer.json然后运行

composer require doctrine/data-fixtures:"dev-doctrinecommon as 1.4.3" --dev

composer require orm-fixtures --dev
