“pip install mariadb”指出它在我的 Windows 10 桌面上找不到包含文件“mysql.h”

Question

我在我的电脑上以管理员身份运行 cmd.exe。然后输入：

pip install mariadb

，但这是它显示的输出：

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for mariadb
Failed to build mariadb
ERROR: Could not build wheels for mariadb, which is required to install pyproject.toml-based projects

为什么会出现这种情况？

我将 Visual C++ 更新到最新版本，我的 python 版本是 3.13，pip 是 24.0 版本，来自

C:\Python313\Lib\site-packages\pip

。

有人可以帮我吗？

您可能缺少 MariaDB Connector/C 库和头文件。前往官方下载网站并安装先决条件选项卡中列出的所有内容。

那么你应该可以走了！
