从今天早上开始我无法在Symfony中更新我的供应商包。我得到以下错误:
PHP Fatal error: Class 'Composer'Script'PackageEvent' not found in phar:///var/bean/deploy/qa/2013-06-03/api/composer.phar/src/Composer/Script/EventDispatcher.php on line 78

有谁知道是什么引起的吗?如果我将symfony切换到最新的2.3版本，这个问题就会得到解决，但我现在不想这样做。
问题是APC操作码缓存。我通过运行命令行手动下载了composer:
php -r "eval('?>'.file_get_contents('https://getcomposer.org/installer'));"
并且在运行该命令时，它通知我:
The apc.enable_cli setting is incorrect.
Add the following to the end of your `php.ini`:
apc.enable_cli = Off
所以我把它关掉了，一切都很好。
