设置Shopware 6失败时出现PHP错误

Question

目前在我的Ubuntu机器上设置Shopware 6社区版( https://www.shopware.com/de/download/ )。

我遵循以下步骤：https://docs.shopware.com/de/shopware-6-de/erste-schritte/shopware-6-installieren

我还有所有的要求：https://docs.shopware.com/de/shopware-6-de/erste-schritte/systemvoraussetzungen

我的机器：

• Ubuntu 18.04.3 LTS
• PHP 7.2.19-0ubuntu0.18.04.2
• Apache 2.4.29

我创建了apache2配置并遵循了设置，包括数据库的设置。一切都很顺利。但是，当我试图访问页面myshopdomain.tld/admin时，我只接收到一个空白页面，在开发人员控制台中有500个内部服务器错误，显示GET请求(它不像javascript调试消息那样被记录)。当查看在apache2配置中配置的错误日志时，我看到以下内容：

有人知道如何修复这个错误吗？

Answer 1

确保在名为php7.2-xml的发行版上安装了PHP扩展。如果这不能解决问题，您几乎肯定需要Shopware开发人员的帮助。
