<p><code>rustup</code> 是 Rust 的安装程序，也是它的版本管理程序。
|
|
|
强烈建议使用 <code>rustup</code> 来安装 Rust，当然如果你有异心，请寻找其它安装方式，然后再从下一节开始阅读。</p>
|
|
|
<blockquote>
|
|
|
<p>haha，开个玩笑。读者乃大大，怎么能弃之不顾。</p>
|
|
|
<p>注意：如果你不想用或者不能用 rustup，请参见 <a href="https://forge.rust-lang.org/infra/other-installation-methods.html#other-rust-installation-methods">Rust 其它安装方法</a>。</p>
|
|
|
</blockquote>
|
|
|
<p>至于版本，现在 Rust 稳定版特性越来越全了，因此下载最新稳定版本即可。由于你用的 Rust 版本可能跟本书写作时不一样，一些编译错误和警告可能也会有所不同。</p>
|
|
|
<h2 id="在-linux-或-macos-上安装-rustup"><a class="header" href="#在-linux-或-macos-上安装-rustup">在 Linux 或 macOS 上安装 <code>rustup</code></a></h2>
|
|
|
<p>打开终端并输入下面命令：</p>
|
|
|
<pre><code class="language-console">$ curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh
|
|
|
</code></pre>
|
|
|
<p>这个命令将下载一个脚本并开始安装 <code>rustup</code> 工具，此工具将安装 Rust 的最新稳定版本。可能会提示你输入管理员密码。</p>
|
|
|
<p>如果安装成功，将出现下面这行：</p>
|
|
|
<pre><code class="language-text">Rust is installed now. Great!
|
|
|
</code></pre>
|
|
|
<p>OK，这样就已经完成 Rust 安装啦。</p>
|
|
|
<h3 id="安装-c-语言编译器非必需"><a class="header" href="#安装-c-语言编译器非必需">安装 C 语言编译器：（非必需）</a></h3>
|
|
|
<p>Rust 对运行环境的依赖和 Go 语言很像，几乎所有环境都可以无需安装任何依赖直接运行。但是，Rust 会依赖 <code>libc</code> 和链接器 <code>linker</code>。所以如果遇到了提示链接器无法执行的错误，你需要再手动安装一个 C 语言编译器：</p>
|
|
|
<p><strong>macOS 下：</strong></p>
|
|
|
<pre><code class="language-console">$ xcode-select --install
|
|
|
</code></pre>
|
|
|
<p><strong>Linux 下：</strong></p>
|
|
|
<p>Linux 用户一般应按照相应发行版的文档来安装 <code>GCC</code> 或 <code>Clang</code>。</p>
|
|
|
<p>例如，如果你使用 Ubuntu，则可安装 <code>build-essential</code>。</p>
|
|
|
<h2 id="在-windows-上安装-rustup"><a class="header" href="#在-windows-上安装-rustup">在 Windows 上安装 <code>rustup</code></a></h2>
|
|
|
<p>Windows 上安装 Rust 需要有 <code>C++</code> 环境，以下为安装的两种方式：</p>
|
|
|
<p><strong>1. <code>x86_64-pc-windows-msvc</code>（官方推荐）</strong></p>
|
|
|
<p>先安装 <a href="https://visualstudio.microsoft.com/zh-hans/visual-cpp-build-tools/">Microsoft C++ Build Tools</a>，勾选安装 C++ 环境即可。安装时可自行修改缓存路径与安装路径，避免占用过多 C 盘空间。安装完成后，Rust 所需的 msvc 命令行程序需要手动添加到环境变量中，否则安装 Rust 时 <code>rustup-init</code> 会提示未安装 Microsoft C++ Build Tools，其位于：<code>%Visual Studio 安装位置%\VC\Tools\MSVC\%version%\bin\Hostx64\x64</code>（请自行替换其中的 %Visual Studio 安装位置%、%version% 字段）下。</p>
|
|
|
<p>如果你不想这么做，可以选择安装 Microsoft C++ Build Tools 新增的“定制”终端 <code>Developer Command Prompt for %Visual Studio version%</code> 或 <code>Developer PowerShell for %Visual Studio version%</code>，在其中运行 <code>rustup-init.exe</code>。</p>
|
|
|
<p>准备好 C++ 环境后开始安装 Rust：</p>
|
|
|
<p>在 <a href="https://www.rust-lang.org/learn/get-started">RUSTUP-INIT</a> 下载系统相对应的 Rust 安装程序，一路默认即可。</p>
|
|
|
<pre><code class="language-shell">PS C:\Users\Hehongyuan> rustup-init.exe
|
|
|

|
|
|
<p><strong>2、<code>x86_64-pc-windows-gnu</code></strong></p>
|
|
|
<p>相比于 MSVC 版本来说，GNU 版本具有更轻量，更靠近 Linux 的优势。</p>
|
|
|
<p>首先，根据 <a href="https://www.msys2.org/">MSYS2 官网</a> 配置 MSYS。</p>
|
|
|
<p>若您觉得下载太慢，可以试试由 <a href="https://github.com/Caviar-X">Caviar-X</a> 提供的 <a href="https://github.pigeons.icu/msys2/msys2-installer/releases/download/2021-11-30/msys2-x86_64-20211130.exe">代理</a>。</p>
|
|
|
<p>在安装 <code>mingw-toolchain</code> 后，请将 <code>%MSYS 安装路径%\mingw64\bin</code> 添加到系统变量 <code>PATH</code> 中。</p>
|
|
|
<p>配置好后，在 MSYS 中输入下面的命令来安装 rustup。</p>
|
|
|
<pre><code class="language-bash">$ curl https://sh.rustup.rs -sSf | sh

|
|
<p>如果没看到此信息：</p>
|

|
<ol>
|
|
|
<li>如果你使用的是 Windows，请检查 Rust 或 <code>%USERPROFILE%\.cargo\bin</code> 是否在 <code>%PATH%</code> 系统变量中。</li>

<h2 id="本地文档"><a class="header" href="#本地文档">本地文档</a></h2>
