  ERROR: Failed building wheel for mysqlclient

DEPRECATION: Could not build wheels for mysqlclient which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

我该怎么办？提前感谢大家。

MySQL提供了他们自己版本的MySQL适配器- python连接器，这是一个全在的MySQL模块，它使用MySQL应用编程接口，没有C模块依赖，只使用标准的python模块。

它可以在CloudLinux CageFS中运行，无需安装任何模块或修改任何配置。
