使用 Composer 在 PHPOffice PHPSpreadSheet 上安装错误

Question

我正在使用 Windows 10 和 Laragon 5.0 WAMP（PHP 7.4.19 和 Apache 2.4.47）。

正在尝试使用以下命令安装 PHPOffice/PHPSpreadSheet Composer：

composer require phpoffice/phpspreadsheet

Composer 安装没有问题，但是当尝试运行这个 PHP 代码时：

<?php
$spreadsheet = \PhpSpreadsheet\IOFactory::load('template.xlsx');

$worksheet = $spreadsheet->getActiveSheet();

$worksheet->getCell('A1')->setValue('John');
$worksheet->getCell('A2')->setValue('Smith');

$writer = \PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xls');
$writer->save('write.xls');
?>

出现错误：

Fatal error: Uncaught Error: Class 'PhpSpreadsheet\IOFactory' not found in C:\laragon\www\excel.php:2 Stack trace: #0

我哪里做错了？

请帮忙，谢谢

正确代码：

<?php

require __DIR__ .  '/vendor/autoload.php'; /* will vary depending upon your environment */
$spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load('template.xlsx');

$worksheet = $spreadsheet->getActiveSheet();

$worksheet->getCell('A1')->setValue('John');
$worksheet->getCell('A2')->setValue('Smith');

$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xls');
$writer->save('write.xls');

?>

使用 Windows 文件资源管理器、PHPOffice 文件夹和安装在 C:\Users\user\vendor

上的 autoload.php 文件进行搜索

C:\laragon\www

中的 Laragon Apache htdocs 文件夹

将 require __DIR__ . '/vendor/autoload.php'; 更改为 require "C:/Users/user/vendor/autoload.php";，它终于起作用了
