Question

我正在使用Symfony 2.4和doctrine mongodb bundle开发一个应用程序。我遇到了一个令人讨厌的错误：

ClassNotFoundException：尝试从/opt/apps/aff/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Cursor.php中的命名空间“Symfony \ Component \ Debug \ Exception”加载类“FlattenException”第455行。您是否需要从其他命名空间“使用”它？也许你需要为以下之一添加一个use语句：Symfony \ Component \ HttpKernel \ Exception \ FlattenException，Symfony \ Component \ Debug \ Exception \ FlattenException。

特别是在访问sonata admin bundle的列表方法时会发生此错误。我在玩存储库classess时也遇到过这个错误。

确切的代码在远程服务器上运行良好。但是在本地机器上出现了这个错误。我不知道为什么。我在终端上运行了以下代码，以查看版本号或git commit ref代码。

$ php composer.phar show -i

两台计算机上的结果完全相同。以下是我的composer.json

}

我真的很困惑，我不知道如何处理。这个恼人的例外是什么意思？

我有同样的事情，错误是由Cursor.php中的hint（）方法中的错误参数类型强制的。并且PHP的PHP严格标准错误设置正在为此创建错误。这可能是它在远程服务器上正常工作的原因（不同的PHP设置）。

现在问题已解决，因此更新MongoDB供应商应该解决它。 More information
