title: Composer: install package directly, via command line
body: <p>I need to install <a href="https://github.com/jarektkaczyk/eloquence" rel="nofollow noreferrer">sofa/eloquence</a> Laravel <strong>5.2</strong> package. In the documentation there is the following instruction:</p>
  
  <pre><code>1. Require the package in your composer.json:
  
      "require": {
          "sofa/eloquence": "~5.2", // for Laravel 5.2.*
      },
  </code></pre>
  
  <p>So, I guess that after requiring it in <strong>composer.json</strong> I will have to run the <code>composer update</code> command. But, this command will also try to update other packages that are already installed, right? </p>
  
  <p>What if I don't want that, how can I install <code>"sofa/eloquence": "~5.2"</code> without touching anything else? For example, directly, via command line (or in any other way).</p>
