无法安装RabbitMQ Symfony

Question

我正在尝试安装到我的项目RabbitMq包中，我使用的是php7.4.9.我可以在Ubuntu上安装rabbitMQ服务器，但现在Symfony出现了问题

我还想问，突然你在OOP中遇到了一个很好的例子，我想写出好的代码

tanyaPC:  composer require php-amqplib/rabbitmq-bundle

Using version ^1.14 for php-amqplib/rabbitmq-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.

  Problem 1
    - php-amqplib/rabbitmq-bundle v1.14.4 requires symfony/dependency-injection ^2.7|^3.0|^4.0 -> no matching package found.
    - php-amqplib/rabbitmq-bundle v1.14.3 requires symfony/dependency-injection ^2.7|^3.0|^4.0 -> no matching package found.
    - php-amqplib/rabbitmq-bundle v1.14.2 requires symfony/dependency-injection ^2.7|^3.0|^4.0 -> no matching package found.
    - php-amqplib/rabbitmq-bundle v1.14.1 requires symfony/dependency-injection ^2.7|^3.0|^4.0 -> no matching package found.
    - php-amqplib/rabbitmq-bundle v1.14.0 requires symfony/dependency-injection ^2.7|^3.0|^4.0 -> no matching package found.
    - Installation request for php-amqplib/rabbitmq-bundle ^1.14 -> satisfiable by php-amqplib/rabbitmq-bundle[v1.14.0, v1.14.1, v1.14.2, v1.14.3, v1.14.4].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.
 - It's a private package and you forgot to add a custom repository to find it

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

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

我试图在互联网上解决这个问题，但我没有发现，我真的希望你能帮助我

这是我的composer.json

Answer 1

Problem

上面写着

requires symfony/dependency-injection ^2.7|^3.0|^4.0

但同时你也有

Restricting packages listed in "symfony/symfony" to "5.1.*"

所以它是不兼容的。

可能的解决方案1

你把Symfony的所有东西都写成“旧的”，比如

        "symfony/console": "^4.4.0|^5.0.0|^5.1.0",

    ...

    "extra": {
        "symfony": {
            "allow-contrib": false,
            "require": "4.4.*"
        }
    }

(可能会被优化)，这可能会起作用。

可能的解决方案2

由于该包已有一段时间没有更新，而您使用的是Symfony的新版本，因此更好的方法可能是使用symfony/messenger。
