我已经尝试了几种方法

  • pip install opencv-contrib-python（无法安装任何作品）
  • pip install mysqlclient==1.3.12（显示相同的错误）
  • 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“非常快”，但是现在MySQL连接问题已经用了4天了。）

似乎您的构建工具无法处理某些.h文件。您可以使用unofficial precompiled package database来获取已编译的mysqlclient。 下载后运行

pip install name-of-whl-file.whl

如果whl文件的python + win版本无法安装，请尝试使用其他版本。如果构建工具失败，总是对我有用。

答案 1 :(得分：1)

您下载了错误的车轮。错误消息表明您尝试安装mysqlclient-1.4.2-cp38-cp38m-win_amd64.whl，该命令适用于Python 3.8。

由于您使用的是Python 3.7，因此应根据安装的是32位还是64位Python使用mysqlclient‑1.4.2‑cp37‑cp37m‑win32.whl或mysqlclient‑1.4.2‑cp37‑cp37m‑win_amd64.whl。

答案 2 :(得分：0)

当我尝试在Windows中安装mysqlclient时，出现了相同的错误。在此错误上花费了大量时间后。我在安装最新的Visual Studio和Visual Studio构建工具的结果中发现了一个结果。如果是程序员并且仅从事编码工作，则将Windows转移到Ubuntu上的ubuntu.i转移并享受编码

答案 3 :(得分：0)

尝试一下：

pip install mysqlclient-1.4.4-cp38-cp38-win_amd64.whl

如果它不起作用，请使用32位版本

 pip install mysqlclient-1.4.4-cp38-cp38-win32.whl

答案 4 :(得分：0)

安装mysql-client的最好方法是转到https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient，您会发现很多mysql-client wheel。

  • 下载第一个＃不要更改文件名，
  • 打开命令提示符，
  • 使用cd转到您的车轮安装目录，
  • 然后也使用pip install（文件名）#use .whl

如果它不起作用，请下载第二个，然后重复该过程，如果还是不行，请继续下载，直到我保证您至少会在计算机中安装其中一个。
