安装FriendsOfCake / cakephp-csvview后缺少控制器异常

Question

我使用安装了FriendsOfCake/cakephp-csvview

php ../composer.phar require friendsofcake/cakephp-csvview:~3.0.

之后，即使在bootstrap.php注释掉Plugin::load('CsvView')之后，所有页面也都显示Missing Controller Exception （肯定Plugin::load('CsvView') 。 我怀疑php无法找到控制器类，但不知道为什么。 我用过find . -mtime -1 find . -mtime -1 ， src下的任何文件均未更改。

谁能告诉我Cakephp如何确定类文件的位置，以便我进行故障排除？

堆栈跟踪如下：

如果有的话，CakePHP仅尝试从较短的类名中找出完全合格的类名，而不处理类文件或确定它们的位置，从CakePHP 3开始，它依赖于作曲家自动加载器 （ vendor/autoload.php ）来做到这一点。

如果在更新依赖项后事情中断了，这也将导致自动加载器重新转储，则很有可能自动加载器发生故障（无论出于何种原因）。
