<p><code>cargo install</code>命令用于在本地安装和使用二进制 crate。它并不打算替换系统中的包；它意在作为一个方便 Rust 开发者安装他人在 crates.io 共享的工具的手段。只有有二进制目标文件的包能够安装，而且所有二进制文件都被安装到 Rust 安装根目录的 <em>bin</em> 文件夹中。如果你使用 <em>rustup.rs</em> 安装的 Rust 且没有自定义任何配置，这将是<code>$HOME/.cargo/bin</code>。将这个目录添加到<code>$PATH</code>环境变量中就能够运行通过<code>cargo install</code>安装的程序了。</p>
|
|
|
|
|
|
<p>例如，第十二章提到的叫做<code>ripgrep</code>的用于搜索文件的<code>grep</code>的 Rust 实现。如果想要安装<code>ripgrep</code>，可以运行如下：</p>
|
|
|
|
|
|
<pre><code>$ cargo install ripgrep
|
|
|

|
</code></pre>
|
|
|
|
|
|
<p>最后一行输出展示了安装的二进制文件的位置和名称，在这里<code>ripgrep</code>被命名为<code>rg</code>。只要你像上面提到的那样将安装目录假如<code>$PATH</code>，就可以运行<code>rg --help</code>并开始使用一个更快更 Rust 的工具来搜索文件了！</p>
