应用报错RuntimeError: Could not locate a supported Microsoft Visual C++ installation解决方法

python应用在安装时报错，部分错误信息如下：

在安装 tiny-cuda-nn 时，找不到支持的 Microsoft Visual C++ 编译器，解决方法：

首先检查电脑是否安装Microsoft Visual Studio及【使用C++的桌面开发】模块

VS 2022微软官网下载链接https://visualstudio.microsoft.com/zh-hans/downloads/

如果是电脑上已经安装了VS的话，那应该是没有安装到默认路径，比如C盘以外，我安装到了E盘里，所以这个地方报错了，将cl.exe路径添加到系统环境变量path中即可，如我的电脑上cl.exe路径地址：E:\Microsoft\2022\VC\Tools\MSVC\14.40.33807\bin\Hostx64\x64，你可以根据参考找到你的路径地址添加到系统环境变量中，重新运行应用或cmd窗口即可
