我目前正在尝试在 RHEL8 服务器上安装适用于 python2.7 的 MySQLdb。
当尝试通过 pip 安装模块时

我还通过 pip 安装了以下模块：
setuptools (44.1.1)
mysql-connector-python (8.0.23)
pip (9.0.3)
您有机会建议我在这里缺少什么吗？ 预先感谢！
MySQLdb 对于您的新 MySQL 来说太旧了。请参阅https://pypi.org/project/MySQL-python/：
MySQL-3.23 通过 5.5 …目前支持
我的建议是尝试以下其中一项：
https://pypi.org/project/mysqlclient/
pip install "mysqlclient<2.0"
https://pypi.org/project/mysql-connector-python/
pip install mysql-connector-python
https://pypi.org/project/PyMySQL/
pip install "PyMySQL<1.0"
使用以下补丁使 MySQL-python 能够与较新版本的 MySQL 尤其是 MariaDB 一起使用：
