为什么composer不能解决依赖关系？

Question

我有两个私有的但桶存储库，它们涉及到一个冲突：

• Bi腺/yii2-模型-目录(目前为1.0.19)
• bigland/yii2-模型-概念-计划(目前为1.0.5)

如果我在bigland/yii2-models-conceptual-plan存储库中运行composer update --一切都很好。

如果我在bigland/yii2-models-catalogue存储库中运行composer update -我有以下错误：

  Problem 1
    - bigland/yii2-models-conceptual-plan dev-master requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
    - bigland/yii2-models-conceptual-plan 1.0.3 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
    - bigland/yii2-models-conceptual-plan 1.0.2 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
    - bigland/yii2-models-conceptual-plan 1.0.1 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
    - bigland/yii2-models-conceptual-plan 1.0.5 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
    - bigland/yii2-models-conceptual-plan 1.0.4 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
    - Installation request for bigland/yii2-models-conceptual-plan @dev -> satisfiable by bigland/yii2-models-conceptual-plan[1.0.4, 1.0.5, 1.0.1, 1.0.2, 1.0.3, dev-master].

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.

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

为什么会发生这种事？

Answer 1

你对循环的依赖不是很奇怪吗？A -> B -> A

Answer 2

解决方案如下:将循环依赖版本替换为dev-master，而不是1.0.x。

bi腺体/yii2-模型-目录Conmposer.json

"bigland/yii2-models-conceptual-plan": "dev-master"

bigland/yii2-models-conceptual-plan Composer.json

"bigland/yii2-models-catalogue": "dev-master"
