嗨，我想更新我的项目2.5.10到2.7，但我不能这样做。我换了作曲家。json
...
"symfony/symfony": "2.7.*",
...
执行编辑器更新时显示如下异常:
作曲家更新用包信息加载编写器存储库更新依赖项(包括require-dev)

在这个文件中，我们添加了一些变化，不知道是否正确100%
最近更新了我的站点到Symfony 2.7
首先，你少了一个逗号，即>=0.90，<3.0这应该能回答你的问题。
第二，最好的升级方式是下载Symfony标准发行包并比较composer。因为Symfony版本可能不是你唯一需要升级的东西。
第三，可能只是顺便说一下，一旦我通过composer更新了我的2.7 Symfony网站，我总是得到一个没有错误日志的白屏。我在Github上提出了这个问题，当你安装了APC缓存时，升级Sensio发行包显然会导致这个问题。重新启动Apache，清理缓存解决了这个问题。
编码快乐!
你可以像这样修改json文件的require-dev部分
"require-dev": {
"twig/twig": "~1.5",
"doctrine/doctrine-bundle": "~1.2",
"doctrine/orm": "~2.2,>=2.2.3",
"swiftmailer/swiftmailer": ">=4.3,<6.0",
"symfony/yaml": "~2.3",
"symfony/validator": "~2.3",

这是我的工作
