【问题描述】：

我在 Symfony 5 中开始了一个新项目，并尝试使用 composer require easycorp/easyadmin-bundle 安装 EasyAdmin，但我发现了一个问题。

作曲家日志：

./composer.json has been updated

你有解决办法吗？

【参考方案1】：

正如您在错误消息列表中看到的那样：easycorp/easyadmin-bundle 在 v2 中需要 doctrine/common，而您已经安装了 v3。

您应该降级该软件包，以便可以安装管理包。如果您需要这方面的帮助，请将composer.json 的内容添加到您的问题中。

【讨论】：

感谢您的帮助，终于明白了！但是当我尝试升级时，其他依赖项存在问题...

如果升级有其他问题，请为此开新问题

【参考方案2】：

Easyadmin 依赖于教义/通用 v2，您需要使用 composer remove doctrine/common 删除当前的教义版本，然后您可以安装 easyadmin

【讨论】：

感谢您的帮助，我也尝试过，但是其他依赖项存在问题...

只需对其他依赖项应用相同的过程

【参考方案3】：

尝试像这样更改您的 composer.json 文件：

    "type": "project",
    "license": "proprietary",
    "require": 
        "php": ">=7.2.5",
        "ext-ctype": "*",
        "ext-iconv": "*",
        "composer/package-versions-deprecated": "^1.11",
        "doctrine/annotations": "^1.10",
        "doctrine/doctrine-bundle": "^2.1",
        "doctrine/doctrine-migrations-bundle": "^3.0",
        "doctrine/orm": "^2.6.3",
    "easycorp/easyadmin-bundle": "3.1",
        "sensio/framework-extra-bundle": "^5.6",
        "symfony/asset": "5.1.*",
        "symfony/console": "5.1.*",
        "symfony/dotenv": "5.1.*",
        "symfony/flex": "^1.3.1",
        "symfony/form": "5.1.*",
        "symfony/framework-bundle": "5.1.*",
        "symfony/maker-bundle": "^1.20",
        "symfony/security-bundle": "5.1.*",
        "symfony/stopwatch": "5.1.*",
        "symfony/twig-bundle": "5.1.*",
        "symfony/validator": "5.1.*",
        "symfony/web-profiler-bundle": "5.1.*",
        "symfony/yaml": "5.1.*",
        "twig/extra-bundle": "^2.12|^3.0",
        "twig/twig": "^2.12|^3.0"
    ,

然后输入：sudo composer update。适用于 Ubuntu 18.04 LTS :)

【讨论】：

请解释什么你做了什么改变以及为什么。此外，除非您有充分的理由，否则不应使用 sudo 运行 composer

我已经更改了学说的版本：“doctrine/orm”：“^2.6.3”，并添加了：“easycorp/easyadmin-bundle”：“3.1”，然后一定要更新作曲家。

请通过编辑将所有此类解释添加到您的答案中

【参考方案4】：

你需要降级学说/普通和学说/坚持。

试试这个：

composer require doctrine/persistence:1.3.8 doctrine/common:2.13.3

那么你应该可以调用：

symfony composer req "admin:^2.0"
