我需要下载Cython来将py编译成c，结果在pip install的时候报错这个：

去你要下载的依赖包的官网上直接找whl文件，我这里拿Cython举例，记得找对应python版本和对应python架构的，我这里使用的是32位的python

下载完成之后直接运行命令就行了：

pip install Cython-3.0.11-cp313-cp313-win32.whl

如果你使用了conda记得提前激活对应的环境，否则可能会提示你以下的错误：

ERROR: Cython-3.0.11-cp313-cp313-win32.whl is not a supported wheel on this platform.
