Json 拉威尔5.7级'；照明\Support\Facades\Lang'；找不到

我最近遇到了这个错误：

Class 'Illuminate\Support\Facades\Lang'not found 
{"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Class 'Illuminate\\Support\\Facades\\Lang' 
    not found at vendor/laravel/framework/src/Illuminate/Auth/Notifications/ResetPassword.php:60)

我必须更改代码表：

return (new MailMessage)
    ->subject(Lang::getFromJson('Reset Password Notification'))
    ->line(Lang::getFromJson('You are receiving this email because we received a password reset request for your account.'))
    ->action(Lang::getFromJson('Reset Password'), url(config('app.url').route('password.reset', $this->token, false)))
    ->line(Lang::getFromJson('If you did not request a password reset, no further action is required.'));

致：

这是可行的，但每次更新后我都要这么做

文件vendor\laravel\framework\illumb\Support\Facades\Lang.php：

<?php

namespace Illuminate\Support\Facades;

/**
 * @method static mixed trans(string $key, array $replace = [], string $locale = null)
 * @method static string transChoice(string $key, int|array|\Countable $number, array $replace = [], string $locale = null)
 * @method static string getLocale()
 * @method static void setLocale(string $locale)
 * @method static string|array|null get(string $key, array $replace = [], string $locale = null, bool $fallback = true)
 *
 * @see \Illuminate\Translation\Translator
 */
class Lang extends Facade
{
    /**
     * Get the registered name of the component.
     *
     * @return string
     */
    protected static function getFacadeAccessor()
    {
        return 'translator';
    }
}

像@ceejayoz suggest一样，删除供应商文件夹并运行
composer安装
解决了问题

谢谢大家的帮助
 在
vendor/laravel/framework/src/illusted/Support/Facades/Lang.php中是否有文件？是的，文件存在。我首先尝试清除
vendor
并重新安装
composer
。这将防止权限问题，并为您提供一组干净的文件。
composer install
将重新生成
vendor
目录。如果删除vendor目录，则会重新生成该目录<代码>供应商
不应包含手动修改的代码，因此删除它并使用
composer安装重新生成它
应修复任何依赖性问题，正如ceejayoz多次建议的那样。
