我无法使用 Composer 安装 stof/doctrine-extensions-bundle
.我使用的是 Symfony2.1.9 版本,出现了很多问题.第一个是:
I can't install stof/doctrine-extensions-bundle
with my Composer. I'm using Symfony2.1.9 version and a lot of problems are shown. The first one is:
找不到请求的包 stof/doctrine-extensions-bundle 1.1.*.
the requested package stof/doctrine-extensions-bundle 1.1.* could not be found.
这是我的 composer.json
文件:
{
"name": "symfony/framework-standard-edition",
"description": "The "Symfony Standard Edition" distribution",

"extra": {
"symfony-app-dir": "app",
"symfony-web-dir": "web",
"branch-alias": {

}
}
}
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一组可安装的软件包
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
请问可能是什么问题?我应该先安装 DoctrineExtensions 吗????
what could be the problem please?? should i install DoctrineExtensions first????

推荐答案
这里的关键部分如下:
[...]
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].
[...]
这会导致混乱!让我解释一下:
Which can lead to confusion! Let me explain:
虽然它说可以通过将 symfony/symfony 更新到 2.2.0 或 2.2.1 来满足依赖关系......这个更新是 不需要 !!(即使更新可能是个好主意,也没有必要解决问题,并且可能由于 BC [向后兼容性] 中断而导致代码损坏)
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 )
注意:
许多包都有一个legacy 分支 ...例如一个2.1.x 分支来支持symfony/symfony 2.1.
Many bundles have a legacy branch ... for example a 2.1.x branch to support symfony/symfony 2.1.
在盲目地将整个项目更新到根包的新版本之前,请在 packagist 上查找这些分支!
Look for these branches on packagist prior to blindly updating your whole project to a new version of the root package!
提示:
通常,如果 composer 无法获取依赖项,这通常与您所需软件包之一的最低稳定性有关.所有包的最低稳定性通常默认为 stable.
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.
解决方案:
smarttech 为 white-october/pagerfanta-bundle 使用了错误的分支 (dev-master) 以将其与 symfony 2.1 一起使用.2.1 的 正确分支 应该是:
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"
... @dev 稳定性标志告诉作曲家为这个单一包使用 dev 版本的学说扩展包.请阅读更多关于 composer 的 稳定性标志的信息.
... 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.
快速浏览一下稳定性层次结构:
dev < alpha < beta < rc < stable
替代方案:
解决问题的另一种方法是设置 composer 的 最低稳定性.
Another way to solve the issue would have been setting composer's minimum stability.
虽然这是不推荐,因为它适用于所有约束,因此您将获得所有包的不稳定版本.
Though this is not recommended as it applies to all constraints and as a result you will get unstable versions of all packages.
