Laravel错误调用未定义的方法Pelago \ Emogrifier :: disableInvisibleNodeRemoval（）

Question

我正在gitlab中克隆laravel Web-api项目。然后，我想迁移并服务以便在邮递员中测试api。但是，当我进行迁移或服务时，会出现错误

In CssInlinerPlugin.php line 18:

Call to undefined method Pelago\Emogrifier::disableInvisibleNodeRemoval()

有人可以帮我吗？我不知道如何解决这个问题，因为即使Google也没有答案。预先感谢。

CssInlinerPlugin.php

<?php

namespace Snowfire\Beautymail;

class CssInlinerPlugin implements \Swift_Events_SendListener
{
    /**
     * @var \Pelago\Emogrifier
     */
    protected $inliner;

    /**
     * Initialize the CSS inliner.
     */
    public function __construct()
    {
        $this->inliner = new \Pelago\Emogrifier();
        $this->inliner->disableInvisibleNodeRemoval();
    }

    /**
     * Inline the CSS before an email is sent.
     *
     * @param \Swift_Events_SendEvent $evt
     */
    public function beforeSendPerformed(\Swift_Events_SendEvent $evt)
    {
        $message = $evt->getMessage();

        $properTypes = [
            'text/html',
            'multipart/alternative',
            'multipart/mixed',
        ];

        if ($message->getBody() && in_array($message->getContentType(), $properTypes)) {
            $this->inliner->setHtml($message->getBody());
            $message->setBody($this->inliner->emogrify());
        }

        foreach ($message->getChildren() as $part) {
            if (strpos($part->getContentType(), 'text/html') === 0) {
                $this->inliner->setHtml($part->getBody());
                $message->setBody($this->inliner->emogrify());
            }
        }
    }

    /**
     * Do nothing.
     *
     * @param \Swift_Events_SendEvent $evt
     */
    public function sendPerformed(\Swift_Events_SendEvent $evt)
    {
        // Do Nothing
    }

似乎该软件包对此有未解决的问题：https://github.com/Snowfire/Beautymail/issues/111他们在这里列出了几个解决方案。也许尝试将版本更改为2.2.0？
