我要在Amazon的AWS Lightsail系统上安装Magento。我已经安装了NGINX，MySQL和PHP

但是我一直收到此错误：

Answer 1

您需要安装php-dom和php-xml软件包，但是从您的PHP信息看来。您已经这样做了。如果您使用的是Debian或Ubuntu，则可以通过运行apt install php-dom php-xml

来确保

您可能需要重新启动PHP FPM或Apache才能使更改生效-例如。 systemctl restart php-fpm或systemctl restart apache2（或systemctl restart httpd）

Answer 2

是的，必须在 ec2-user 的腻子上使用命令“sudo yum install php-dom php-xml”安装“php-dom php-xml”。我使用命令 sudo yum install php-dom php-xml 安装它对我来说就像一种魅力。

Magento：找不到类“ DOMDocument”
