欢迎提出任何建议

我假设您正在尝试安装Magento 2.4

在PHP中似乎没有必需的LIB。示例中安装了ext intl。请办理登机手续：

php -i |grep ext-intl

请在最后也检查一下

php --ini

---

将两个结果粘贴到此处。

尝试重新安装所有PHP扩展-

sudo apt get安装php7.4-gd php7.4-mcrypt php7.4-curl php7.4-intl php7.4-xsl php7.4-mbstring php7.4-openssl php7.4-zip php7.4-soap

---

你的确切问题是什么？对于给定的错误消息是否有任何不清楚的地方？是否有更好的解决方案来安装magento 2.4？那么您尝试安装哪个版本？最新版本是2.4.0。检查需求。Magento 2.3不支持PHP7.4。如果你想尝试学习m2.4。如果你想让它投入生产，现在就用2.3

7.1.3+，7.2.x->Magento 2.3.x

~7.4.0->Magento 2.4.0

啊，好的，所以我必须降级或卸载PHP7.4，当我想安装Magento的稳定/生产版本时？我感觉你对Magento是新手。这是一个很棒的平台，是最好的电子商务平台。这并不意味着它完美且容易学习。这需要自我克制。不要轻易放弃。您的问题的答案是：当前的稳定版本是2.4.0，它运行在PHP7.4上。去做吧。非常感谢你的激励！好的，我试试看。
