Ich weiß nicht, was ich mit dem Fehler machen sollte. Bitte helfen Sie mir, dieses Problem zu lösen.

Answer 1

Sie müssen die DOM-Funktionen für PHP installieren (wie durch die Fehlermeldung angezeigt phpunit/php-code-coverage 4.0.8 requires ext-dom * -> the requested PHP extension dom is missing from your system.)

Das sieht (aus der Ausgabe von Erweiterungen) wie eine Debian-basierten Maschine. apt install php7.0-xml sollte es Ihnen ermöglichen, fortzufahren.

Answer 2

In Zend Framework 2, Standard-Mail-Paket wird dort sein, können Sie einfach dieses Stück Code verwenden.,

use Zend\Mail; 

$mail = new Mail\Message(); 
$mail->setBody('This is the text of the email.'); 
$mail->setFrom('Freeaqingme@example.org', 'Sender\'s name'); 
$mail->addTo('Matthew@example.com', 'Name o. recipient'); 
$mail->setSubject('TestSubject'); 

$transport = new Mail\Transport\Sendmail(); 
$transport->send($mail);
