<p>使用 Rust 的第一步是安装。你需要联网来执行本章的命令，因为我们要从网上下载 Rust。</p>
|
|
|
<p>我们将会展示很多使用终端的命令，并且这些代码都以<code>$</code>开头。并不需要真正输入<code>$</code>，它们在这里代表每行指令的开头。在网上会看到很多使用这个惯例的教程和例子：<code>$</code>代表以常规用户运行命令，<code>#</code>代表需要用管理员运行的命令。没有以<code>$</code>（或<code>#</code>）的行通常是之前命令的输出。</p>
|

|
<a class="header" href="#在-linux-或-mac-上安装" name="在-linux-或-mac-上安装"><h3>在 Linux 或 Mac 上安装</h3></a>
|
|
|
<p>如果你使用 Linux 或 Mac，所有需要做的就是打开一个终端并输入：</p>
|
|
|
<pre><code class="language-sh">$ curl https://sh.rustup.rs -sSf | sh
|
|
|
</code></pre>
|
|
|
<p>这会下载一个脚本并开始安装。你可能被提示要输入密码。如果一切顺利，将会出现如下内容：</p>
|
|
|
<pre><code class="language-sh">Rust is installed now. Great!
|
|
|
</code></pre>
|
|
|
<p>当然，如果你不赞成<code>curl | sh</code>这种模式，可以随意下载、检查和运行这个脚本。</p>
|
|
|
<a class="header" href="#在-windows-上安装" name="在-windows-上安装"><h3>在 Windows 上安装</h3></a>
|
|
|
<p>在 Windows 上，前往<a href="https://rustup.rs/">https://rustup.rs</a><!-- ignore -->并按照说明下载<code>rustup-init.exe</code>。运行并遵循它提供的其余指示。</p>
|
|
|
<p>本书其余 Windows 相关的命令假设你使用<code>cmd</code>作为你的 shell。如果你使用不同的 shell，可能能够执行 Linux 和 Mac 用户相同的命令。如果都不行，查看所使用的 shell 的文档。</p>
|
|
|
<a class="header" href="#自定义安装" name="自定义安装"><h3>自定义安装</h3></a>
|
|
|
<p>如果有理由倾向于不使用 rustup.rs，请查看<a href="https://www.rust-lang.org/install.html">Rust 安装页面</a>获取其他选择。</p>
|
|
|
<a class="header" href="#卸载" name="卸载"><h3>卸载</h3></a>
|
|
|
<p>卸载 Rust 同安装一样简单。在 shell 中运行卸载脚本</p>
|
|
|
<pre><code class="language-sh">$ rustup self uninstall
|
|
|
</code></pre>
|
|
|
<a class="header" href="#故障排除" name="故障排除"><h3>故障排除</h3></a>
|
|
|
<p>安装完 Rust 后，打开 shell，输入：</p>
|
|
|
<pre><code class="language-sh">$ rustc --version
|
|
|
</code></pre>
|
|
|
<p>应该能看到类似这样的版本号、提交 hash 和提交日期，对应你安装时的最新稳定版本：</p>
|
|
|
<pre><code class="language-sh">rustc x.y.z (abcabcabc yyyy-mm-dd)
|
|
|
</code></pre>
|
|
|
<p>如果出现这些内容，Rust 就安装成功了！</p>
|
|
|
<p>恭喜入坑！（此处应该有掌声！）</p>
|
|
|
<p>如果有问题并且你在使用 Windows，检查 Rust（rustc，cargo 等）是否位于<code>%PATH%</code>系统变量中。</p>
|
|
|
<p>如果还是不能运行，有许多可以获取帮助的地方。最简单的是 irc.mozilla.org 上的 IRC 频道 <a href="irc://irc.mozilla.org/#rust-beginners">#rust-beginners</a> 和供一般讨论之用的 <a href="irc://irc.mozilla.org/#rust">#rust</a>，我们可以使用 <a href="http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-beginners,%23rust">Mibbit</a> 访问。然后我们就可以和其他能提供帮助的 Rustacean（我们这些人自嘲的绰号）聊天了。其它给力的资源包括<a href="https://users.rust-lang.org/">用户论坛</a>和<a href="http://stackoverflow.com/questions/tagged/rust">Stack Overflow</a>。</p>
|
|
|
<a class="header" href="#本地文档" name="本地文档"><h3>本地文档</h3></a>
|
|
|
<p>安装程序也包含一份本地文档的拷贝，你可以离线阅读它们。输入<code>rustup doc</code>将在浏览器中打开本地文档。</p>
|
|
|
<p>任何你太确认标准库提供的类型或函数是干什么的时候，使用文档 API 查找！</p>
