我对composer和symfony完全陌生，我已经开始了一个symfony3项目。事情进展顺利，但现在作曲家不会更新我的依赖关系。我已经搜索了3个小时的解决方案。
这是我的控制台日志：
Problem 1
- sonata-project/admin-bundle dev-master requires sonata-project/block-bundle 3.x-dev@dev -> satisfiable by sonata-project/block-bundle[3.x-dev] but these conflict with your requirements or minimum-stability.
- sonata-project/admin-bundle dev-master requires sonata-project/block-bundle 3.x-dev@dev -> satisfiable by sonata-project/block-bundle[3.x-dev] but these conflict with your requirements or minimum-stability.
- Installation request for sonata-project/admin-bundle dev-master -> satisfiable by sonata-project/admin-bundle[dev-master].
我的composer.json需求：
"require": {
"php": ">=5.5.9",
"symfony/symfony": "3.0.*",
"doctrine/orm": "^2.5",
"doctrine/doctrine-bundle": "^1.6",
"doctrine/doctrine-cache-bundle": "^1.2",
"symfony/swiftmailer-bundle": "^2.3",
"symfony/monolog-bundle": "^2.8",
"sensio/distribution-bundle": "^5.0",
"sensio/framework-extra-bundle": "^3.0.2",
"incenteev/composer-parameter-handler": "^2.0",
"friendsofsymfony/user-bundle": "dev-master",
"sonata-project/admin-bundle": "dev-master",
"sonata-project/doctrine-orm-admin-bundle": "dev-master"
},
如果你能找到问题并向我解释，你将成为我的英雄！
默认情况下，composer通过定义stable的最小稳定性，只安装包的稳定版本，即使您要求dev版本提供其中一个。
要告诉composer您允许安装开发版本（如dev-master），
在您的要求后添加以下行：
"minimum-stability": "dev"
注意：实际上必须使用最新版本的奏鸣曲捆绑包。
