title: Lumen Composer cannot detect vendor folder in newly created project
body: <p>When creating new Lumen project using:</p>
  
  <pre><code>lumen new blogb
  </code></pre>
  
  <p>New directory is being created but <strong>vendor</strong> folders not occurs in newly created folder. </p>
  
  <p>That way when I try</p>
  
  <pre><code>php artisan serve
  </code></pre>
  
  <p>I get following errors (because there is no vendor folder):</p>
  
  <blockquote>
    <p>Warning:
    require_once(C:\Users\user\Desktop\blogb\bootstrap/../vendor/autoload.php):
    failed to open stream: No such file or directory in
    C:\Users\user\Desktop\blogb\bootstrap\app.php on line 3</p>
    
    <p>Fatal error: require_once(): Failed opening required
    'C:\Users\user\Desktop\blogb\bootstrap/../vendor/autoload.php'
    (include_path='.;C:\php\pear') in
    C:\Users\user\Desktop\blogb\bootstrap\app.php on line 3</p>
  </blockquote>
  
  <p>EDIT: <strong>laravel new blog</strong> command works ok, and application can be run, but problem happens when <em>lumen new blog</em> is being executed. </p>
