PHP致命错误：未捕获错误：Class'；蛋糕\\lib\\Dispatcher'；找不到

我正在Ubuntu 18.04 LTS上运行Apache2.4.29和PHP7.2。我的数据文件（/var/www/cake/prod/webroot/）是从Apache2.2.20迁移而来的，在Ubuntu11.10上运行PHP5

我的apache服务运行正常，但当我尝试访问网站（）时，它显示： 我的ip当前无法处理此请求。

我检查Apache错误日志，并显示以下错误消息：

[Fri Dec 20 05:52:47.177805 2019][php7:error][pid 10916][client ip:19466]PHP致命错误：未捕获错误：在/var/www/cake/prod/webroot/index.PHP中找不到类“Dispatcher”。PHP:82\n堆栈跟踪：\n#0{main}\n在第82行的/var/www/cake/prod/webroot/index.PHP中抛出

根据
index.php
文件，此版本的CakePHP与php版本4和5兼容，服务器上安装了php 7.2

您应该将CakePHP更新到与PHP7.2兼容的最新可用版本。
您是否从另一台服务器复制了该站点？如果是这样的话，您是从
/var/www/cake
复制了所有内容，还是只是从
/var/www/cake/prod/webroot
复制了所有内容？另外，这运行的是什么版本的CakePHP？apache配置与您的问题无关。这看起来像是CakePHP的旧版本，看起来很匹配。
include\u path
设置为什么，该路径中是否存在文件？实际上，根据错误，禁用了
ini\u set
，您需要显式地包含Dispatcher类。我已复制了/var/www/cake中的所有文件。这是下一个要面对的问题（），但这并没有解决（隐含的）问题问到为什么第一次尝试加载类失败的问题。cakephp版本是4.0.0i，包含行
require LIBS'php'错误消息是：
[[php7:warn][pid 26159][client:23707]PHP警告：使用未定义的常量LIBS-假定为'LIBS'（这将在PHP的未来版本中引发错误），位于/var/www/cake/prod/webroot/index.PHP的第82[][php7:warn][pid 26159][client:23707]PHP警告：require（LIBSdispatcher.PHP）：无法打开流：第82行的/var/www/cake/prod/webroot/index.php中没有这样的文件或目录
