如何在首次使用php、nginx和mysql安装magento 2时解决错误

Question

我正试图通过Ubuntu在我的windows 10机器上安装Magento 2。到目前为止，我已经成功地安装了PHP7.4、MySQL 8.0和NGINX。在安装Magento 2时，我得到以下错误-

我正在遵循链接- https://www.simicart.com/blog/magento-2-nginx/#Step_4_Configure_nginx中提供的指南。在指南中执行步骤7时，我得到了错误。

我试着研究这些错误，但都指向了升级中的一个问题，而这是我第一次安装magento。我继续执行步骤8，但仍然得到了相同的错误集。

Answer 1

请您运行这个并粘贴输出好吗？

php -m

我快速地看了一下指南，它似乎并没有告诉您安装Magento 2所需的所有PHP扩展。

指南中有两个不同的步骤#7。如果您被困在第二个命令中，请运行以下命令并在这里发布输出：

sudo systemctl status nginx
