Question

我使用

安装了

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

Plugin::load('CsvView')

之后所有页面都显示缺少控制器异常（他们肯定没问题），即使在bootstrap.php中注释掉find . -mtime -1之后也是如此。我怀疑php无法找到控制器类，但不知道为什么。我使用了src，2016-10-04 03:20:39 Warning: Headers already sent in {base}/vendor/cakephp/cakephp/src/Error/Debugger.php:753 2016-10-04 03:20:39 Error: [Cake\Routing\Exception\MissingControllerException] Controller class Holders could not be found.

有谁能告诉我Cakephp如何计算出类文件的位置，以便我可以排除故障？

如果有的话，CakePHP只会尝试从较短的类中找出完全限定的类名，它不处理包含类文件或计算它们的位置，从CakePHP 3开始它依赖于composer autoloader（{{1} }）这样做。

如果在更新依赖项后事情中断，这也会导致自动加载器被重新转储，那么自动加载器破坏的可能性很大（无论出于何种原因）。
