Dompdf laravel邮件附件在服务器中出现问题

我已经在我的laravel应用程序中使用dompdf创建了一个自动发票生成选项，它在我的本地pc上运行良好，但在我的服务器上，它在我的日志文件和作业队列中出现以下错误也失败了。我在作业队列文件中添加了pdf生成选项，它在我的本地主机中看起来非常好

这是我的进口货

有人能帮忙吗？

根据您的异常

production中的这一行。错误：找不到类“Dompdf\Cpdf”

，似乎

Dompdf\Cpdf

的导入部分不正确。你能把你的控制器代码粘贴到你使用这个类的地方吗？我已经在这里添加了它，我正在我的作业队列文件中这样做。你在顶部的导入是什么样子的？我用我的导入进行了编辑，将你的PDF导入改为：

use Barryvdh\DomPDF\Facade as PDF
