gd - 安装了 php-gd 但无法在 centos 7(php 7.3 版本)中运行

Question

我正在尝试安装 moodle，但它显示缺少/应该启用 php-gd 扩展。然而，gd 已经安装并且是最新的，当我命令 php -v 时，我收到以下错误，如下所示。

PHP Warning:  PHP Startup: Unable to load dynamic library 'gd.so' (tried: /usr/lib64/php/modules/gd.so (/lib64/libraqm.so.0: undefined symbol: hb_ft_font_set_load_flags), /usr/lib64/php/modules/gd.so.so (/usr/lib64/php/modules/gd.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

我做了很多编辑，但找不到单一的解决方案。请帮忙

我遇到了同样的问题:

# php --version
PHP Warning:  PHP Startup: Unable to load dynamic library 'gd' (tried: /usr/lib64/php/modules/gd (/usr/lib64/php/modules/gd: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/gd.so (/lib64/libraqm.so.0: undefined symbol: hb_ft_font_set_load_flags)) in Unknown on line 0

在 google 中快速搜索告诉我 hb_ft_font_set_load_flags 来自 HarfBuzz ( https://harfbuzz.github.io/harfbuzz-hb-ft.html )。

我用 yum install harfbuzz 安装了它，然后警告消失了:
