安装C++编译工具（如下图所示）
可以通过设置环境变量，将rust安装到自己设置的目录中，不设置安装到默认的路径C:\Users\用户名\.rust中。
- RUSTUP_HOME
- CARGO_HOME
第1步中输入：x86_64-pc-windows-gnu 后面直接回车即可，最后安装输入1
打开命令提示符窗囗，输入如下命令进行验证：
rustc --version
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
安装过程中，需要选择1，2，3，输入1进行默认安装即可，如下所示：
[root@localhost ~]# curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Welcome to Rust!
This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.
Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:
/root/.rustup
This can be modified with the RUSTUP_HOME environment variable.
The Cargo home directory is located at:
/root/.cargo
This can be modified with the CARGO_HOME environment variable.
The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:
/root/.cargo/bin
This path will then be added to your PATH environment variable by
modifying the profile files located at:
/root/.profile
/root/.bash_profile
/root/.bashrc
You can uninstall at any time with rustup self uninstall and
these changes will be reverted.

Rust is installed now. Great!
To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).
To configure your current shell, run:
source "$HOME/.cargo/env"
source $HOME/.cargo/env
[root@localhost ~]# rustc -V
bash: rustc: command not found... #环境未生效
[root@localhost ~]# source $HOME/.cargo/env #使环境生效
[root@localhost ~]# rustc -V
rustc 1.64.0 (a55dd71d5 2022-09-19) #环境已生效，得到版本信息
[root@localhost ~]# cargo --version
cargo 1.64.0 (387270bc7 2022-09-16)
