title: Laravel - Composer detected issues in your platform after updating it
body: <p>So i just updated composer using the command <code>composer self-update --2</code>,
  However, now my web application shows the error <code>Composer detected issues in your platform: Your Composer dependencies require a PHP version &quot;&gt;= 7.3.0&quot;.</code></p>
  <p>I dont understand this because doing <code>php -v</code> gives me PHP 7.4.13</p>
  <p>How can I fix this?</p>
