首先需要安装MSYS2
官网的安装exe下载非常慢，去国内高校镜像站下载
https://mirrors.ustc.edu.cn/msys2/distrib/x86_64/msys2-x86_64-20260322.exe
如果是安装x86版本的qemu，就是官方网页说的，使用pacman安装
pacman -S mingw-w64-x86_64-qemu
如果是其它架构的，去base package查看：
https://packages.msys2.org/base/mingw-w64-qemu
aarch64的包可能是下面这个
$ pacman -S mingw-w64-clang-aarch64-qemu warning: mingw-w64-clang-aarch64-qemu-10.2.2-1 is up to date -- reinstalling resolving dependencies... looking for conflicting packages... Packages (1) mingw-w64-clang-aarch64-qemu-10.2.2-1 Total Installed Size: 1040.87 MiB Net Upgrade Size: 0.00 MiB :: Proceed with installation? [Y/n] y /usr/share/libalpm/scripts/mingw-w64-clang-aarch64-gtk-update-icon-cache.script: line 5: /clangarm64/bin/gtk-update-icon-cache.exe: cannot execute binary file: Exec format error error: command failed to execute correctly
这个其实是错的，这个安装在aarch64 架构的windows版本上的。
其实还是安装这个，x86_64指的host的版本，里面包含了支持各种架构的qemu
$ pacman -S mingw-w64-x86_64-qemu
注意，这个是mingw版本，要在MINGW64版本的MSYS2运行
