**2、x86_64-pc-windows-gnu**
该类型的C++ 环境其实官方也有说明 [Other Rust Installation Methods](https://forge.rust-lang.org/infra/other-installation-methods.html#other-rust-installation-methods).
个人习惯使用 [mingw-w64 官网](https://www.mingw-w64.org/) , 当然你也可以选择[win-builds](http://win-builds.org/).
为了方便初学者使用 这里提供一个免安装的的方式 [mingw-w64下载](https://sourceforge.net/projects/mingw-w64/files/),演示选择的 `x86_64-posix-seh` 对于学习者,初次安装不需要纠结什么类别,因为切换版本很方便。下载完压缩包并解压,把压缩包下的 `/bin` 目录添加到 环境`Path` 即可:

1、验证 c++ 环境
``` shell
PS C:\Users\Hehongyuan> c++ -v
Using built-in specs.
COLLECT_GCC=C:\ENV\mingw64\bin\c++.exe
COLLECT_LTO_WRAPPER=C:/ENV/mingw64/bin/../libexec/gcc/x86_64-w64-mingw32/8.1.0/lto-wrapper.exe
Target: x86_64-w64-mingw32
Configured with: xxxxxxxxxxxxxx
gcc version 8.1.0 (x86_64-posix-seh-rev0, Built by MinGW-W64 project)
```
2、安装 Rust 注意选择 `Customize installation` 并设置 `host triple``x86_64-pc-windows-gnu`
``` shell
PS C:\Users\Hehongyuan> rustup-init.exe
......
Current installation options:
default host triple: x86_64-pc-windows-msvc
default toolchain: stable (default)
profile: default
modify PATH variable: yes
1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

I m going to ask you the value of each of these installation options.
You may simply press the Enter key to leave unchanged.
Default host triple? [x86_64-pc-windows-msvc]
x86_64-pc-windows-gnu
Default toolchain? (stable/beta/nightly/none) [stable]
相比于msvc版本来说gnu版本具有更轻量更靠近linux的优势
### 更新和卸载
Profile (which tools and data to install)? (minimal/default/complete) [default]
首先,根据[MSYS2官网](https://www.msys2.org/)配置MSYS
配置好后在MSYS中输入
```bash
curl https://sh.rustup.rs -sSf | sh
```
来安装rustup
> windows上安装过程较为麻烦因此我们专门写了一篇文章来讲解相关的安装过程请参考[Windows安装](https://blog.csdn.net/erlib/article/details/121684998?spm=1001.2014.3001.5501).
### 更新和卸载
之后,根据以下输出进行配置
通过 `rustup` 安装 Rust 后,更新到最新版本很简单。在终端中运行以下更新命令:
```console
$ rustup update
```
配置完成后,您就已经安装了 `Rust``rustup`
要卸载 `Rust``rustup`,在终端中运行以下卸载命令:
要卸载 `Rust``rustup`在MSYS中运行以下卸载命令
```console
$ rustup self uninstall
```bash
rustup self uninstall
```
