我在安装 Symfony 2.3.7 时遇到依赖问题。这是一个全新的 Symfony 安装，下载 2.3.7，没有 Vendors zip。运行 composer update 进行初始安装。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"
},

以及来自“php composer.phar update”的错误

我认为这里有问题，你有 symfony > 2.3，但评论需要 < 2.3

friendsofsymfony/comment-bundle v2.0.5 requires symfony/symfony >=2.1,<2.3-dev

尝试安装此版本的评论

"friendsofsymfony/comment-bundle": "2.0.*@dev"

在composer.json中使用此标志（不需要，强制所有依赖项开发最后一个开发版本）

"minimum-stability": "dev"

前两行解释了一切：

Friendsofsymfony/comment-bundle v2.0.4 需要 jms/serializer 1.0.*@dev -> 找不到匹配的包。

看看你的作曲家，json，你有 0.13。@dev，不是 1.0。@dev

symfony/framework-bundle 2.0.7 需要 symfony/translator 2.0.7 -> 找不到匹配的包。

查看您的 composer.json，您安装的是 2.3.*，而不是 2.0。

我认为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，您可以稍后添加 "jms/serializer-bundle": "0.13.*@dev" 如果需要。
