Symfony 2.2 到 2.4 升级麻烦，找不到 setDispatcher()

Question

我使用 Symfony 2.2 已经有一段时间了，最​​近决定升级到 2.4。

运行作曲家更新后，我收到此错误消息。框架似乎由于未知原因无法找到“setDispatcher()”方法。

./composer.phar update
Loading composer repositories with package information
Updating dependencies (including require-dev)
....
Writing lock file
Generating autoload files
PHP Fatal error:  Call to undefined method Symfony\Bundle\FrameworkBundle\Console\Application::setDispatcher() in vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Console/Application.php on line 86
Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-update-cmd event terminated with an exception



  [RuntimeException]                                                         
  An error occurred when executing the "'cache:clear --no-warmup'" command.

我一直在搜索，但找不到任何类似的问题。

也许有人以前见过这样的事情。这是我的composer.json。我认为问题可能与此文件有关。

好的，我发现了导致错误的原因。控制台版本太旧导致加载错误的类产生上述错误。

更换

"symfony/console": "2.2.*@dev",

与

"symfony/console": "2.5.*@dev",

解决了问题。
