我已经尝试了几种方法

• pip install opencv-contrib-python(可以安装不行)
• pip install mysqlclient==1.3.12(显示同样的错误)
• 我从 Wheel Link 安装 mycsqlclient| (显示此错误 mysqlclient-1.4.2-cp38-cp38m-win_amd64.whl is not a supported wheel on this platform.)

我的python版本是:3.7.3

(我来自桌面环境，当我阅读 Django 时，它说“快得离谱”，但现在 MySQL 连接问题已经花了 4 天)。

Answer 1

您下载了错误的轮子。错误消息说您尝试安装适用于 Python 3.8 的 mysqlclient-1.4.2-cp38-cp38m-win_amd64.whl。

由于您使用的是 Python 3.7，因此您应该使用 mysqlclient‑1.4.2‑cp37‑cp37m‑win32.whl 或 mysqlclient‑1.4.2‑cp37‑cp37m‑win_amd64。 whl 取决于您安装的是 32 位还是 64 位 Python。
