python - VSCode，为什么我在尝试将 mysqlclient 安装到 django 项目时出现错误

Question

我正在尝试将 mysql 集成到 django 项目，但是当我尝试 pip install mysqlclient VSCode 抛出此错误:

有人知道我该如何解决这个问题吗？我已经安装了 Microsoft Visual C++ 包版本 14.22。

Answer 1

latest release of mysqlclient有适用于 Windows 的轮子，但它们适用于 64 位。如果您安装的是 64 位 Windows，我将通过安装 64 位版本的 Python 来解决此问题。否则，这似乎是 sdist 中的一个错误，其中头文件被意外遗漏。
