这是链接mysql库文件的gcc默认功能吗？我已经在谷歌上搜索过了，它显示gcc需要as。所以我需要将其与某个位置进行符号链接。我正在服务器上运行mariadb 10.9，但在我的系统中没有找到任何此类文件 打开终端或使用ssh客户端登录到工作站/笔记本电脑/dev服务器。以root用户身份键入以下命令yum command：

它在抱怨找不到mariadb libs。运行以下命令以找出原因：
ld -lmariadb --verbose
debian / ubuntu: sudo apt-get install python-dev libmysqlclient-dev
redhat / centos: sudo yum install python-devel mysql-devel
sudo yum install MariaDB-devel
$ yum list installed | grep mariadb

> pkg-config --libs mariadb
-lmariadb
sudo ln -s /usr/lib64/libmariadbclient.a /usr/lib64/libmariadb.a
sudo yum install -y python36-devel mysql-devel gcc
sudo ln -s /usr/lib64/libmariadbclient.a /usr/lib64/libmariadb.a
pip install mysqlclient
对我来说最简单的解决方案是：
yum install python-devel mysql-devel
pip install mysqlclient
我的问题是如何安装所有这些文件，而不是检查是否安装了这些文件，因为此命令给我提供了以下信息：
