title: Composer not installing local package dependencies
body: <p>In my Laravel 5.4 composer.json file I have the following that autoloads my custom package. Note, that this package is not published and is being loaded locally.</p>
  
  <pre><code>"autoload": {
      "classmap": [
          "database/seeds",
          "database/factories"
      ],
      "psr-4": {
          "App\\": "app/",
          "Vendor\\Module\\": "packages/vendor/module/src"
      }
  },
  </code></pre>
  
  <p>And then in my package composer.json file I have the following</p>
  
  <pre><code>{
      "name": "vendor/module",
      "description": "A custom package",
      "version": "1.0.0",
      "type": "project",
      "authors": [
      ],
      "minimum-stability": "dev",
      "require": {
        "laravelcollective/html": "^5.4.0"
      }
  }
  </code></pre>
  
  <p>However, when I run <strong>composer install</strong> from the root Laravel directory, it never picks up the laravelcollective/html package that I am requiring.</p>
  
  <p>Is there a way to load in dependencies on a local package that is not published?</p>
