php - 从作曲家包中找不到php类

问题描述

我安装了这个包composer require konekt/pdf-invoice，但标准use在调用它时找不到该类。

然后在我的脚本中我正在使用：

<?php
include "includes/basics.php" ;
use Konekt\PdfInvoice\InvoicePrinter;


function genPDF($id) {
  $invoice = new InvoicePrinter();
  ...
  ...
}
?>

并产生错误：
PHP Fatal Error: Uncaught Error: Class 'Konekt\PdfInvoice\InvoicePrinter' not found in wBilling.php:511

在我的/home/userID/php/vendor/konekt/pdf-invoice存在中，据我所知，composer.json 文件已正确定义
