由于 PHP XML 错误，设置 Shopware 6 失败

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

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

我也有所有要求：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。一切顺利。但是当我尝试访问页面 [myshopdomain.tld]/admin 时，我只在开发人员控制台中收到一个空白页，其中包含 500 内部服务器错误，显示 GET 请求（它没有像 javascript 调试消息那样记录下来）。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？

答案1

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