如何解决在 CloudLinux 上安装 mysqlclient 的错误？

Question

我正在尝试在具有 CloudLinux 许可证的 cpanel 上部署我的烧瓶应用程序，我需要一些模块，但是当我尝试安装 mysqlclient 和 flask-mysqldb 时出现错误，我发现人们有很多这个模块的问题，我已经看到了如何修复它，但是在 Ubuntu、Debian 等中......我想知道如何在 CloudLinux 中修复它，这是我输入 pip install mysqlclient 时出现的错误：

  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？提前谢谢大家。

MySQL 提供了他们自己版本的 MySQL 适配器 - MySQL 连接器，这是一个使用 MySQL API 的全功能 python 模块，不依赖 C 模块，只使用标准 python 模块。

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