title: Can't install Laravel Elixir with npm install in Vagrant environment
body: <p>I installed Laravel with Scotch Box and I want to use <strong>gulp</strong> so I can automate some tasks but when I try to install Elixir with npm install I get the following output (created a gist, because it was too long to paste here): <a href="https://gist.github.com/ZiggyV/9f353a4a44ff8f2fa229" rel="nofollow">npm install output</a>.</p>
  
  <p>The only thing that keeps returning in all my attempts to fix this error is this line:</p>
  
  <blockquote>
    <p>npm WARN optional dep failed, continuing fsevents@1.0.2</p>
  </blockquote>
  
  <p>I already tried to use <code>npm install --no-bin-links</code> and I also tried to remove the node_modules folder from my project and run <code>npm cache clean</code> and then <code>npm install</code> again. Both of these methods didn't work either.</p>
  
  <p>The only thing that works is <code>npm install bootstrap-sass</code>. This will install my bootstrap modules but when I try to install Elixir with <code>npm install laravel-elixir</code> I get the same error.</p>
  
  <p>My package.json looks like this:</p>
  
  <pre><code>{
    "private": true,
    "devDependencies": {
      "gulp": "^3.8.8"
    },
    "dependencies": {
      "laravel-elixir": "^3.0.0",
      "bootstrap-sass": "^3.0.0"
    }
  }
  </code></pre>
  
  <p>Node version in my VM</p>
  
  <pre><code>vagrant@scotchbox:~$ node -v

  </code></pre>
  
  <p>Npm version</p>
  
  <pre><code>vagrant@scotchbox:~$ npm -v
  2.14.8
  </code></pre>
  
  <p>Gulp version</p>
  
  <pre><code>vagrant@scotchbox:~$ gulp -v
