删除rustup重装
环境变量配置：
通过RUST_HOME指定rustup的安装目录。
通过CARGO_HOME指定cargo的安装过目录。
再次运行rustup-init文件
观察到安装界面的rustup路径和和cargo已经发生改变；
重复之前的步骤安装即可；
最后检查是否安装成功了；
运行：
$ rustc --version
明显是ok的；
中文非官方的翻译文档（入坑教程文档）：

安装官网的示例教程，新建一个demo
Cargo run的时候报错了；
由于不做c#开发，而且安装vs开发工具太大了，磁盘空间紧张所以用一下方法会更好：
参考：https://www.jianshu.com/p/718626d561ce
rustup uninstall toolchain stable-x86_64-pc-windows-msvc
rustup toolchain install stable-x86_64-pc-windows-gnu (or download rustup-init for the platform of your choice at https://forge.rust-lang.org/infra/other-installation-methods.html)
rustup default stable-x86_64-pc-windows-gnu
用vscode打开的话只要安装几个插件就可以运行编译rust了
从网上下载项目构建后，发生了错误；百度后还是觉得要重新安装好vc++才行，避免后面又遇到一些坑；

索性从新下载，最后还是选择下载vs2022
Cmd重新安装
rustup toolchain install stable-x86_64-pc-windows-msvc
rustup default stable-x86_64-pc-windows-msvc
Ps:当遇到编译问题编译不过时排查：
1网络问题（是当前网络不佳，还是资源依赖不存在了；也可尝试切换替国内的换镜像源）。2工具链问题（可以尝试切换工具链再重新编译一波）
