如何解决外部包的作曲家包循环依赖关系

Question

参见 Github 问题，这个问题的起源。

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

---

我正在尝试将phpdocumentor/reflection-docblock更新到较新的phpunit/phpunit依赖项，该依赖项开始使用我更新的软件包。

有新的循环依赖关系：

• (此(phpdocumentor/reflection-docblock包需要phpunit/phpunit
• phpunit/phpunit需要phpspec/prophecy(自 phpunit/phpunit 4.5 起(
• phpspec/prophecy需要此phpdocumentor/reflection-docblock(此(包

在抽象中：

• A 需要 B
• B 需要 C(新的！
• C 需要 A

之前 - 作品

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

之后 - 坏了

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

当我运行时：

composer update

作曲家冲突输出：

我试过：

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

有什么想法吗？

Answer 1

添加

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

到phpdocumentor/reflection-docblock的composer.json.

这将允许您使用当前主节点作为满足要求的版本4.x

缺点是。继续使用版本时，您必须更新此部分。
