先查看本地安装的rust信息，打开cmd，输入命令：rustup show 查看，如下所示，我的是：“stable-x86_64-pc-windows-msvc”，需要修改成“stable-x86_64-pc-windows-gnu”就可以了

C:\Users\yzx\Desktop\rust\hello-rust\src> rustup show
Default host: x86_64-pc-windows-msvc
rustup home:  C:\Users\yzx\.rustup

stable-x86_64-pc-windows-msvc (default)
rustc 1.79.0 (129f3b996 2024-06-10)

步骤一：执行“rustup toolchain install stable-x86_64-pc-windows-gnu” 命令下载 ‘stable-x86_64-pc-windows-gnu’，如下所示：

C:\Users\yzx\Desktop\rust\hello-rust\src> rustup toolchain install stable-x86_64-pc-windows-gnu
