  <p>I have tried to installed the version 0.6.1 of <code>barryvdh/laravel-dompdf</code> </p>
  
  <p>Once we run : this command :-</p>
  
  <pre><code>composer require barryvdh/laravel-dompdf 
  </code></pre>
  
  <p>Result :
      Using version 0.6.1 for barryvdh/laravel-dompdf
      ./composer.json has been updated
      loading composer repositories with package information<br>
      updating dependencies (including require-dev)
      nothing to installing and update</p>
  
  <p>Then I tried to run the command: <code>composer update</code>, with the following output:</p>
  
  <pre><code>loading composer repositories with package information  
  updating dependencies (including require-dev)
  nothing to installing and update
  problem 1: this package require php&gt;=5.5.9 but your PHP version (5.4.45) does not satisfy that require
