Typo3缓存刷新异常-如何调试

Question

我在服务器上有一个停靠的TYPO3实例，并尝试手动刷新typo3缓存。因此，我使用以下命令在我的docker容器中执行此操作：

vendor/.bin/typo3cms cache:flush

但是，它会失败并返回以下错误：

[ TYPO3\CMS\Core\Error\Exception ]
Warning: rename(): The first argument to copy() function cannot be a directory in /home/app/vendor/typo3/cms/typo3/sysext/core/Classes/Utility/GeneralUtility.php line 2432

我如何调试它并找出问题所在？

使用-vvv进行完整堆栈跟踪

  [ TYPO3\CMS\Core\Error\Exception ]
  Warning: rename(): The first argument to copy() function cannot be a directory in /home/app/vendor/typo3/cms/typo3/sysext/core/Classes/Utili
  ty/GeneralUtility.php line 2432

Answer 1

这是一个已知问题，已通过version 5.8.6 of the TYPO3 Console修复。

Answer 2

好吧，问题是:如何调试它。即使现在解决了问题，这也可能会有所帮助：

你得到了异常跟踪。您在GeneralUtility.php的2432行设置了一个断点。

如果您已经设置了xdebug，那么您只需要使用适当的选项启动命令行命令，例如使用-e来生成调试信息。

您还可以查看DDEV。我最后一次尝试它时，它很好地运行了调试器，请参阅https://ddev.readthedocs.io/en/stable/users/step-debugging/

我通常将xdebug与PhpStorm结合使用。
