所以我尝试安装 php 模块：mysqli、exif、mbstring 和 dom。但我无法这样做......我显然已经设法使用此命令安装 exif 和 mbstring，但它没有出现在已安装模块的列表中：

而且我也找不到 mysqli 包“未找到匹配项”。我还添加了我能够在 php.ini 文件中安装的内容，但它仍然不起作用。这是 error_log 中的消息之一：
[14-Feb-2024 17:31:47 UTC] PHP Warning: PHP Startup: Unable to load dynamic library 'mbstring.so' (tried: ./mbstring.so (./mbstring.so: cannot open shared object file: No such file or directory), ./mbstring.so.so (./mbstring.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
