I'm trying to install pyodbc for python 3.9.2 (32-bit), however I keep getting the error:我正在尝试为 python 3.9.2（32 位）安装 pyodbc，但我不断收到错误消息：

C:\Users\ICAPP02\AppData\Local\Temp\pip-install-0c78okb8\pyodbc_d782ffa5512448c49f83e214e7ec4434\src\pyodbc.h(19): fatal error C1083: Cannot open include file: 'windows.h': No such file or directory error: command 'C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29910\bin\HostX86\x86\cl.exe' failed with exit code 2 C:\Users\ICAPP02\AppData\Local\Temp\pip-install-0c78okb8\pyodbc_d782ffa5512448c49f83e214e7ec4434\src\pyodbc.h(19): 致命错误 C1083: 无法打开包含文件: 'windows.h': 没有这样的文件或目录错误：命令“C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29910\bin\HostX86\x86\cl.exe”失败，退出代码为 2

I understand I am missing the windows.h C++ header files, but I genuinely cant find them, no longer know where to look, know how many I am missing, or know how they look like.我知道我丢失了 windows.h C++ header 文件，但我真的找不到它们，不再知道去哪里找，不知道我丢失了多少，也不知道它们是什么样子。

Also when I do locate them, do I place them in the folder that is referenced in the error?: C:\Program Files (x86)\Microsoft VisualStudio\2019\Community\VC\Tools\MSVC\14.28.29910\bin\HostX86\x86\cl.exe另外，当我找到它们时，是否将它们放在错误中引用的文件夹中？：C:\Program Files (x86)\Microsoft VisualStudio\2019\Community\VC\Tools\MSVC\14.28.29910\bin\ HostX86\x86\cl.exe

I added a photo of the Visual Studio package I downloaded, perhaps I downloaded the wrong package...我添加了我下载的Visual Studio package的照片，也许我下载错了package ...

For some reason the latest version of pyodbc built a Python 3.9 wheel for 64-bit but not for 32-bit.出于某种原因，最新版本的 pyodbc 为 64 位而不是 32 位构建了 Python 3.9 轮。 However, you can get the 32-bit wheel here:但是，您可以在此处获得 32 位轮：

You can also just install the windows sdk, for your particular windows version, to resolve this issue您也可以只安装 windows sdk，针对您特定的 windows 版本，以解决此问题
