【问题描述】：

这几天我一直在尝试解决这个问题。我正在尝试将我的 Django 项目放在 cPanel 上的 venv 中并安装 mysqlclient。因此，在 Cpanel 上设置我的 Python（版本 = 3.7.8）后，我使用pip install django 和pip install mysqlclient 从终端安装了 Django 版本 3.1.7 和 mysqlclient。但是，当我尝试安装 mysqlclient 时，会弹出此错误。

I have tried some of the guide from , such as `yum install mysql` and sudo commands but to no avail.

Please help. 

【问题讨论】：

嗨，我投票结束了这个问题，因为它不是关于编程，而是关于“系统管理员”的东西，所以它应该放在 Serverfault.com 上。也就是说，在您的托管计划中，您似乎不允许使用gcc，这是安装使用 C 库的 Python 模块所必需的。请咨询您的托管服务提供商是否提供解决方法。此外，您可能可以通过使用“仅限 python”的客户端来解决此问题，请查看 docs.djangoproject.com/en/3.1/ref/databases/…

注意到@MichielB。我会尽快将其删除并参考 serverfault.com。谢谢

@codingnoob 你解决了吗？我被困在里面了。
