Question

我正在尝试安装moodle，但它显示php-gd扩展名丢失/应该启用。但是gd已经安装并且是最新的，当我命令php -v时，出现以下错误，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，但是找不到单个解决方案。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中进行的快速搜索告诉我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：

php --version

Answer 2

运行：

yum install libraqm-devel

[root@* ~]# yum provides '*/libraqm.so*'
Repository epel is listed more than once in the configuration
libraqm-0.7.0-4.el7.x86_64 : Complex Textlayout Library
Repo        : epel
Matched from:
Filename    : /usr/lib64/libraqm.so.0.700.0
Filename    : /usr/lib64/libraqm.so.0



libraqm-devel-0.7.0-4.el7.x86_64 : Complex Textlayout Library
Repo        : epel
Matched from:
Filename    : /usr/lib64/libraqm.so


[root@* ~]# ll /usr/lib64/libraqm.so*
lrwxrwxrwx 1 root root    18 Jul 20 23:20 /usr/lib64/libraqm.so -> libraqm.so.0.700.0
lrwxrwxrwx 1 root root    18 Jul 18 19:00 /usr/lib64/libraqm.so.0 -> libraqm.so.0.700.0
-rwxr-xr-x 1 root root 19792 Jan 11  2020 /usr/lib64/libraqm.so.0.700.0

libraqm.so由libraqm-devel提供。

安装libraqm-devel还将安装提供hb_ft_font_set_load_flags的freetype和harfbuzz。

已安装php-gd，但无法在centos 7（php 7.3版本）中运行
