在 Laravel 包开发中使用 Laravel Excel

如何解决在 Laravel 包开发中使用 Laravel Excel

我是第一次创建自己的 Laravel 包。我创建了一个新项目并在项目中需要 orchestra/testbench。一切正常，我可以在包内运行测试，但我无法在包内使用 Laravel Excel。

在 composer.json 中我添加了

"extra": {
    "laravel": {
        "providers": [
            "Maatwebsite\\Excel\\ExcelServiceProvider"
        ],"aliases": {
            "Excel": "Maatwebsite\\Excel\\Facades\\Excel",}
    }
},"require-dev": {
    "orchestra/testbench": "6.0","PHPunit/PHPunit": "^9.5","maatwebsite/excel": "^3.1"
}

并且还运行了 composer dump-autoload，当我想在我的包中使用 Laravel Excel 时，我尝试了

use Maatwebsite\Excel\Facades\Excel;

class TaxCalculation {

    public function incoMetax(): float
    {
        $table = Excel::import(new TaxImport(),'file.xls');
    }

但是出错了

Illuminate\Contracts\Container\BindingResolutionException: Target class [excel] does not exist.

Excel 似乎无法加载。我还需要执行其他步骤才能使用它吗？
