Class 'Mpdf\Mpdf' 在 Phpspreadsheet 中找不到错误

Question

我正在尝试借助 PHPSpreadsheet 将 excel 文件直接转换为 PDF。但出现错误“Class 'Mpdf\Mpdf' not found”，这是我的代码：

<?php 
  require 'vendor/autoload.php';
  use PhpOffice\PhpSpreadsheet\IOFactory;
  use PhpOffice\PhpSpreadsheet\Worksheet\PageSetup;
  use PhpOffice\PhpSpreadsheet\Reader\Xlsx;
  use PhpOffice\PhpSpreadsheet\Writer\Pdf\Mpdf;

  $reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();
  $reader->setReadDataOnly(true);
  $spreadsheet = $reader->load("excel.xlsx");


  // when I use this MPDF class, I'm getting an error Class \Mpdf\Mpdf not found

  $writer = new \PhpOffice\PhpSpreadsheet\Writer\Pdf\Mpdf($spreadsheet);
  $writer->save("excel.pdf");

请帮助上面的代码。

谢谢

来自 phpspreadsheet 的 documentation:

You must now install a PDF rendering library yourself; but PhpSpreadsheet will work with a number of different libraries.

错误是因为没有安装您要使用的渲染库（在本例中为 mPDF）。只需将 mpdf/mpdf 添加到您的作曲家依赖项中即可。
