title: Maatwebsite import doesnt work in ubunutu
body: <p>When I try to import an excel sheet using Maatwebsite 3.1 version on server which is in Ubuntu, I am getting such type of error.</p>
  
  <blockquote>
    <p>Error:</p>
    
    <p>Maatwebsite \ Excel \ Exceptions \ NoTypeDetectedException</p>
    
    <p>No ReaderType or WriterType could be detected. Make sure you either
    pass a valid extension to the filename or pass an explicit type.</p>
  </blockquote>
  
  <p>Controller</p>
  
  <pre><code>$path = $request-&gt;file('mcafile')-&gt;getRealPath();
  $data = \Excel::import(new UsersImport,$path);
  </code></pre>
  
  <p>But the same import excel code works fine in my local windows machine.
  Every code and file that I upload are same. But works different in local and in server. Can anyone please help.</p>
