我在使用Symfony 2.3.7时遇到了依赖性问题 . 这是一个全新的Symfony安装，下载2.3.7没有Vendors zip . 为初始安装运行composer update . 然后将注释包添加到composer.json并再次运行composer update .
composer.json的require部分，
"require": {
"php": ">=5.3.3",
"symfony/symfony": "2.3.*",
"doctrine/orm": ">=2.2.3,<2.4-dev",
"doctrine/doctrine-bundle": "1.2.*",
"twig/extensions": "1.0.*",
"symfony/assetic-bundle": "2.3.*",
"symfony/swiftmailer-bundle": "2.3.*",
"symfony/monolog-bundle": "2.3.*",
"sensio/distribution-bundle": "2.3.*",
"sensio/framework-extra-bundle": "2.3.*",
"sensio/generator-bundle": "2.3.*",
"incenteev/composer-parameter-handler": "~2.0",
"friendsofsymfony/comment-bundle": "2.0.5"
},
而来自'php composer.phar update'的错误

我认为问题在这里，你有symfony> 2.3，但评论要求<2.3
尝试安装this version条评论
在composer.json中使用此标志（不是必需的，强制所有依赖项为dev last dev版本）
前两行解释了一切：
看着你的作曲家，json，你有0.13 . @ dev，而不是1.0 . @ dev
看看你的composer.json，你已经安装了2.3 . *，而不是2.0 .
我想您尝试安装旧版本的foscommentbundle和旧版本的jms序列化程序包 .
删除行"jms/serializer-bundle"："1.0.@dev"并运行composer update . 这将删除任何旧版本的序列化程序 . 之后，如果需要，您可以稍后添加"jms/serializer-bundle"："0.13.*@dev" .
