Question

您好我想将我的项目2.5.10更新到2.7但我不能这样做。我改变了Composer.json

...
"symfony/symfony": "2.7.*",
...

执行时，作曲家更新会显示此异常：

作曲家更新使用包信息加载composer存储库更新依赖项（包括require-dev）

  [RuntimeException]

  d version string "0.90 <3.0"






  [UnexpectedValueException]

这是我的composer.json文件

在此文件中，我们添加了一些更改，并且不知道是否正确100％

Answer 1

最近将我的网站更新为Symfony 2.7

首先，你缺少一个逗号，即＆gt; = 0.90，＆lt; 3.0这应该回答你的问题。

其次，升级的最佳方法是下载Symfony Standard Distribution软件包并比较composer.json值，因为Symfony版本可能不是您升级所需的唯一内容。

第三，可能只是一个副本，一旦我通过作曲家更新更新我的2.7 Symfony网站，我总是有一个白色屏幕，此后没有错误日志。我在Github上提出了这个问题，并且当你安装了APC缓存时显然升级了Sensio发行版捆绑包导致了这个问题。重新启动Apache以清除缓存解决了它。

快乐的编码！
