Class 'PhpOffice\phpspreadsheet\src\PhpSpreadsheet\Spreadsheet' 未在 Laravel 中找到

Question

在我的 Laravel 项目中，我使用 PhpOffice Spreadsheet 从数据表中以 excel 格式下载数据。

为此，我需要在我的控制器、路由和视图中添加代码。

控制器

我在我的控制器中使用了以下命名空间

<?php

    namespace App\Http\Controllers;

    use PhpOffice\PhpSpreadsheet\Spreadsheet;
    use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
    use PhpOffice\PhpSpreadsheet\Writer\Xls;
    use App\OfferCustomersDataTbl;

    public function export($type) {
        $offer_customer_data = OfferCustomersDataTbl::all();
        $spreadsheet = new Spreadsheet();
        $sheet = $spreadsheet->getActiveSheet();
        $sheet->setCellValue('A1', 'Id');
        $sheet->setCellValue('B1', 'Name');
        $sheet->setCellValue('C1', 'Email');
        $rows = 2;

        foreach($offer_customer_data as $empDetails){
            $sheet->setCellValue('A' . $rows, $empDetails['id']);
            $sheet->setCellValue('B' . $rows, $empDetails['name']);
            $sheet->setCellValue('C' . $rows, $empDetails['email']);
            $rows++;
        }

        $fileName = "emp.".$type;
        if($type == 'xlsx') {
        $writer = new Xlsx($spreadsheet);
        } else if($type == 'xls') {
        $writer = new Xls($spreadsheet);
        }
        $writer->save("export/".$fileName);
        header("Content-Type: application/vnd.ms-excel");
        return redirect(url('/')."/export/".$fileName);
    }

路线

Route::get('/export/{type}', 'OfferCustomersDataController@export');

查看

<a href="{{ url('/') }}/export/xlsx" class="btn btn-info">Export to .xlsx</a>

但是当我点击Download as Excel按钮进行下载时，总是报错

Class 'PhpOffice\phpspreadsheet\src\PhpSpreadsheet\Spreadsheet' not found

但是 Spreadsheet class 就在那个位置，我检查过好几次了。

我想不通的问题在哪里

有人帮忙吗？提前致谢

在命令行中： composer require phpoffice/phpspreadsheet

然后在控制器中：

use PhpOffice\PhpSpreadsheet\Spreadsheet;

使用'namespace'\'classname'，不是绝对的link
