有人可以告诉我如何解决这个问题吗？
Rocketeer 在空目录下安装得很好，但不能与我现有的项目一起安装，不知道为什么。
该安装需要什么？
- Installation request for symfony/console == 2.6.6.0 -> satisfiable by symfony/console[v2.6.6].

为什么不安装？
Zend Skeleton 安装的依赖项在 2.6.6 版本中使用 symfony/console。
"anahkiasen/rocketeer"在~4.2版本中需要"illuminate/console"，而2.5.*版本本身需要"symfony/console"。
Composer 无法安装新软件包，因为已安装的 symfony/console 版本 2.6.6 将被保留，但与新软件包的组件要求不兼容（2.5.* 不允许版本 2.6.6）。
您可以尝试手动添加新包，然后运行 composer update 。如果框架包碰巧在2.5版本中也允许symfony/console，这将解析为一组可安装的包。
