“未找到类'Swift_Mailer‘”

Question

我得到了这个错误，但是Swift_Mailer类存在于MailServiceProvider.php中

/home1/phloxmar/phloxcms/vendor/laravel/framework/src/Illuminate/Mail/MailServiceProvider.php第95行的“类'Swift_Mailer‘找不到”

这是我的MailServiceProvider.php

<?php

我已经试过作曲家了，但错误仍然存在。

检查您是否正确地导入了类，如果您需要这样的内容，您应该签入自动加载：

 require_once __DIR__.'/../vendor/swiftmailer/lib/classes/Swift.php';
 Swift::registerAutoload(__DIR__.'/../vendor/swiftmailer/lib/swift_init.php');

如果没有这些内容，请尝试添加它们并运行

composer dump-autoload
