如何解决作曲家软件包对外部软件包的循环依赖？

Question

请参阅Github问题，这个问题的起源。

我的包是phpdocumentor/reflection-docblock，它不是依赖项。

---

我正在尝试更新phpdocumentor/reflection-docblock为较新的phpunit/phpunit依赖关系，该依赖关系开始使用我更新的软件包。

有新的循环依赖项：

• （这个）phpdocumentor/reflection-docblock包要求phpunit/phpunit
• phpunit/phpunit要求phpspec/prophecy（自phpunit/phpunit4.5开始）
• phpspec/prophecy需要这个phpdocumentor/reflection-docblock（this）包装

概括地说：

• A需要B
• B需要C（新的！）
• C需要A

之前-工作

{
    "require-dev": {
        "phpunit/phpunit": "4.4"
    }
}

后断

{
    "require-dev": {
        "phpunit/phpunit": "4.5"
    }
}

当我跑步时：

composer update

作曲家冲突输出：

我试过了：

• minimum-stability: dev
• 别名 "phpunit/phpunit": "4.5 as 4.4"

任何想法如何解决这个问题？

Answer 1

加

"extra": {
    "branch-alias": {
        "dev-master": "4.x-dev"
    }
}

到composer.json的phpdocumentor/reflection-docblock。

这将允许您使用当前的主版本4.x作为满足要求的版本

缺点是。在继续使用版本时，您将必须更新此部分。
