Symfony - 作曲家更新 - 找不到依赖注入配置类

我们的项目部分由三个捆绑组成，其中两个包括Web后端应用程序和客户前端单页应用程序使用的相关API，最后一个“CoreBundle”是公共资源所在的位置 .

这些bundle都有一个DependencyInjection（DI）bundle子目录，但根本没有Configuration类，因为它们都没有任何特定的配置 . 我们使用文档中建议的DI组件，理论上该项目中没有可能影响配置加载机制的特殊情况 .
这一直运作良好直到现在（Symfony 3.3.2） .

In an intent of updating symfony/symfony from 3.3.2 to 3.4, composer post-install script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache generates 2 exceptions:

在Consistency.php第337行：类Bundle \ CoreBundle \ DependencyInjection \ Configuration \ Configuration未找到Consistency.php第285行：Class Bundle \ CoreBundle \ DependencyInjection \ Configuration \ Configuration not found

异常跟踪：

添加一个Configuration类，其 getConfigTreeBuilder() 方法返回一个新的（"empty"）Treebuilder实例，使异常指出另一个bundle . 我为我们的三个捆绑包做了这个，现在异常指出了一个Sensio自己的捆绑包 .

在Consistency.php第337行：未找到类Sensio \ Bundle \ DistributionBundle \ DependencyInjection \ Configuration \ Configuration ...

以下是在抛出异常之前产生的一些Composer警告：

Dependency "symfony/polyfill-apcu" is also a root requirement, but is not explicitly whitelisted. Ignoring.
…
Package hoa/core is abandoned, you should avoid using it. Use hoa/consistency instead.
Package guzzle/guzzle is abandoned, you should avoid using it. Use guzzlehttp/guzzle instead.

执行 rm -rf var/cache/* 没有帮助 .
仅运行 bin/console cache:clear 会抛出同样的异常 .

既然我们的捆绑实现似乎与这个问题没有任何关系，我甚至不太了解可能是问题的根源 . 也就是说，行“ spl_autoload_call() at n/a:n/a ”看起来很奇怪......可能是某些Symfony依赖应该强制到某些版本......？ （顺便说一句changelog没有提供有用的暗示可能的原因）

谢谢您的帮助 .
