Answer 1

原因
无法打开包含文件：'io.h'：没有这样的文件或目录
这是Visual Studio的问题导致的

解决方法
您需要 windows 10 SDK，下载Visual Studio 构建工具并安装：https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2019

1、Visual C++ 构建工具的核心功能。
2、MSVC 工具集 C++ 2019 v142 (x86,x64)
3、Visual C++ 2019 可再发行更新
4、适用于桌面 C++ 的 Windows 10 SDK (10.0.17763.0)

最后，确保您重新启动 PC
这为我解决了这个问题。谢谢你们的帮助
