composer.json无法解析可安装的程序包集 [英] composer.json fails to resolve installable set of package
问题描述
我不能安装stof / doctrine-extensions-bundle与我的composer.i'm使用Symfony2.1.9版本。很多问题显示。第一个是：请求包stof / doctrine-extensions-bundle 1.1。*无法找到。
这是我的composer.json文件：
{

psr-0：{ src /}
}，

]
}，
extra：{
symfony-app-dir：app，
symfony-web-dir：web，
branch-alias：{
dev-master：2.1-dev
}
}
}
当我将包要求设置为：stof / doctrine-extensions-bundle：1.1。* @ dev
响应是：您的要求无法解析为可安装的程序包集
可能是问题请？？
我应该首先安装DoctrineExtensions ????

这可能会导致混乱！让我解释一下：
虽然它说依赖可以通过更新 symfony / symfony 到2.2.0或2.2.1 ...更新是不需要！ （即使更新可能是一个好主意，没有必要解决这个问题，并可能导致破碎的代码，因为BC [向后兼容性]断裂）
注意：
许多邮件包都有旧版分支 ...例如 2.1.x分支以支持 symfony / symfony 2.1。
在 packagist ，然后将整个项目盲目更新到新版本的根包！
提示：：
通常情况下，如果组合器无法获取依赖关系，这通常与您所需的最低稳定性包。所有包的最低稳定性通常默认为稳定。解决方案： b $ b
smarttech对 white-october / pagerfanta-bundle 使用了错误的分支（dev-master），并将其与symfony 2.1 配合使用。 2.1的正确分支应为：
white-october / pagerfanta-bundle： 2.1.*@dev
...其中 @dev stable标志告诉composer对这个单独的包使用doctrine-extensions-bundle的 dev 版本。请详细了解作曲家的稳定性标记。
快速查看稳定性阶层：
code> dev< α， β， rc < beta
替代方案：
解决问题的另一种方法是设置作曲家的最低稳定性< a>。
虽然这不适用于所有约束，因此不推荐使用 ，结果会得到不稳定版本的 all 包。

when i set the package requirement to: "stof/doctrine-extensions-bundle": "1.1.*@dev"
the response was: your requirement could not be resolved to an installable set of package
what could be the problem please?? should i install DoctrineExtensions first????

The critical part in here is the following:
[...]
white-october/pagerfanta-bundle dev-master requires symfony/framework-bundle >=2.2,<3.0 -> satisfiable by symfony/symfony[v2.2.0, v2.2.1], symfony/framework-bundle[v2.2.0, v2.2.1].
[...]
Which can lead to confusion! Let me explain:
Though it says the dependency is satisfiable by updating symfony/symfony to 2.2.0 or 2.2.1 ... this update is NOT NEEDED !! ( even if updating might be a good idea it is not necessary to resolve the issue and could lead to broken code because of BC [backward compatibility] breaks )
Attention:
Many bundles have a legacy branch ... for example a 2.1.x branch to support symfony/symfony 2.1.
Look for these branches on packagist prior to blindly updating your whole project to a new version of the root package!
Tip:
Generally if composer fails to fetch a dependency this is often related to the minimum stability for one of your required packages. minimum stability of all packages normally defaults to stable.
Solution:
smarttech used the wrong branch (dev-master) for white-october/pagerfanta-bundle to use it with symfony 2.1. The correct branch for 2.1 would have been:
"white-october/pagerfanta-bundle": "2.1.*@dev"
... where the @dev stability flag tells composer to use the dev version of doctrine-extensions-bundle for this single package. Please read more about composer's Stability Flags.
Take a quick look at the stability hierarchy:
dev < alpha < beta < rc < beta
Alternative:
Another way to solve the issue would have been setting composer's minimum stability.
Though this is not recommended as it applies to all constraints and as a result you will get unstable versions of all packages.
