title: could not find driver error when using php artisan migrate
body: <p>I started a new blog project to try Laravel. I followed the tutorial from <a href="https://laracasts.com/series/laravel-from-scratch-2017/episodes/1?autoplay=true" rel="noreferrer">https://laracasts.com/series/laravel-from-scratch-2017/episodes/1?autoplay=true</a> .I changed .env file</p>
  
  <pre><code>DB_DATABASE=homestead 
  DB_USERNAME=homestead 
  DB_PASSWORD=secret
  </code></pre>
  
  <p>to</p>
  
  <pre><code>DB_DATABASE=blog
  DB_USERNAME=root
  DB_PASSWORD=
  </code></pre>
  
  <p>Then type </p>
  
  <p><code>php artisan migrate</code></p>
  
  <p>and get an error</p>
  
  <pre><code>   Illuminate\Database\QueryException  : could not find driver (SQL: select * from information_schema.tables where table_schema = blog and table_name = migrations)
  
    at /home/morilon/php_proj/blog/vendor/laravel/framework/src/Illuminate/Database/Connection.php:664

      663|         catch (Exception $e) {
    &gt; 664|             throw new QueryException(

      667|         }
      668|

  <p>What does that mean <code>could not find driver (SQL: select * from information_schema.tables where table_schema = blog and table_name = migrations) ?</code> 
  After installing PHP i reinstalled MySQL with that commands:</p>
  
  <pre><code>pkg --get-selections | grep mysql
  sudo apt-get remove --purge [everything that came up]
  sudo apt-get autoremove &amp;&amp; sudo apt-get autoclean
  sudo apt-get install mysql-server
  </code></pre>
  
  <p>--Update--</p>
  
  <p>After </p>
  
  <pre><code>sudo apt-get install php-pear php7.2-curl php7.2-dev php7.2-gd php7.2-mbstring php7.2-zip php7.2-mysql php7.2-xml
  </code></pre>
  
  <p>error changes</p>
  
  <pre><code>Illuminate\Database\QueryException  : SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO) (SQL: select * from information_schema.tables where table_schema = blog and table_name = migrations)
  </code></pre>
