title: Cannot remove package phpoffice/phpword. (laravel 5.2)
body: <p>I've been working on a Laravel project. While I'm trying to install some package. I got warned </p>
  
  <blockquote>
    <p>Package phpoffice/phpexcel is abandoned, you should avoid using it.
    Use phpoffice/phpspreadsheet instead.</p>
  </blockquote>
  
  <p>Therefore, I executed the command </p>
  
  <pre><code>composer remove phpoffice/phpexcel
  </code></pre>
  
  <p>The phpoffice/phpexcel has been remove from composer.json successfully.</p>
  
  <p>Then install the package,</p>
  
  <pre><code>composer require phpoffice/phpspreadsheet
  </code></pre>
  
  <p>I still got warned by the same warning,</p>
  
  <blockquote>
    <p>Package phpoffice/phpexcel is abandoned, you should avoid using it.
    Use phpoffice/phpspreadsheet instead.</p>
  </blockquote>
  
  <p>I always got warned by this sentence from every composer command even the phpoffice/phpexcel has been removed from composer.json.</p>
  
  <p>Pls help I really have no idea to remove this warning.</p>
