title: Laravel throws errors when creating new project
body: <p>Good day, I'm following the <a href="https://laravel.com/docs/5.4" rel="nofollow noreferrer">Laravel documation</a> to get started with laravel and start up a new project. My problem is when I through with setting up everything along with add laravel to my path. When I run in my terminal "Laravel new blog" it runs but returns some warnings and errors such as in the picture below:</p>

  <p>I ignored that and went on with the instructions provided in the documentation, which instructed me to run this command "php artisan" to see a list of laravel commands. When I did I got this warning:<a href="https://i.stack.imgur.com/wQthF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wQthF.png" alt="enter image description here"></a></p>
  
  <p>When I check to see the version of php available, this is what I get:</p>
  
  <pre><code>PHP 7.0.18-0ubuntu0.16.04.1 (cli) ( NTS )
  Copyright (c) 1997-2017 The PHP Group

  </code></pre>
  
  <p>Is there a way I can solve this problem? Thanks!!!</p>
