如何解决 Symfony 和 CalendarBundle 的作曲家依赖性？

Question

我想在我的 Symfony2.2 项目中使用 yvoyer/CalendarBundle。

我将它添加到composer.json 并运行：

composer update star/calendar-bundle --prefer-source

它返回这个错误：

$ composer update star/calendar-bundle --prefer-source
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

错误的原因是什么？我正在考虑分叉项目并更改composer.json。但是我应该在上面放什么？

Answer 1

只需阅读错误的前 3 行：

- Conclusion: remove symfony/symfony v2.2.0
- star/calendar-bundle 0.1 requires symfony/symfony 2.0.* -> satisfiable by symfony/symfony[2.0.7, v2.0.10, v2.0.11, v2.0.12, v2.0.13, v2.0.14, v2.0.15, v2.0.16, v2.0.17, v2.0.18, v2.0.19, v2.0.20, v2.0.21, v2.0.22, v2.0.23, v2.0.9].
- star/calendar-bundle 0.1.1 requires symfony/symfony 2.1.* -> satisfiable by symfony/symfony[v2.1.0, v2.1.0-BETA1, v2.1.0-BETA2, v2.1.0-BETA3, v2.1.0-BETA4,v2.1.0-RC1, v2.1.0-RC2, v2.1.1, v2.1.10, v2.1.11, v2.1.2, v2.1.3, v2.1.4, v2.1.5, v2.1.6, v2.1.7, v2.1.8, v2.1.9].

第一行告诉我们symfony/symfony 包的版本是错误的。它下面的 2 行给出了错误的原因：

• 0.1 版需要 Symfony 2.0.x
• 0.1.1 版需要 Symfony 2.1.x

所以不支持 2.2.x。

如果你想在 2.2 中使用这个 bundle，你应该怎么做：

1. fork 捆绑包并使用 sf 2.2 对其进行测试
2. 删除所有已弃用的内容并使其与 2.2 兼容
3. 更新composer.json 以获得类似symfony/symfony: 2.2.* 的内容
4. 请求包含您所做更改的 PR，将其合并并让包的作者创建一个新版本的包并在您的 composer.json 中使用该版本
