我在 Laravel 5.5 中实现邮件时遇到此错误----> Illuminate\Support\Manager::createDriver() 缺少参数 1

I am getting this error while implementing Mail in Laravel 5.5---->Missing argument 1 for Illuminate\Support\Manager::createDriver()

错误 - Illuminate\Support\Manager::createDriver()

缺少参数 1

我的环境文件-

MAIL_DRIVER=smtp
MAIL_HOST=smtp.****.com
MAIL_PORT=587
MAIL_USERNAME=info@*****.com
MAIL_PASSWORD=******
MAIL_ENCRYPTION=tls

config 文件夹 mail.php 中的所有键都是正确的。

我的控制器函数是这样的

function send(Request $request)
    {
        $this->validate($request,[
            'name'=>'required',
            'email'=>'required|email',
            'subject'=>'required',
            'message'=>'min:10'
        ]);

        $data=array(
            'name'=>$request->name,
            'email'=>$request->email,
            'subject'=>$request->subject,
            'bodyMessage'=>$request->message
        );
        Mail::send('mail.admin',$data,function($message) use ($data)
        {
            $message->from($data['email']);
            $message->to($data['info@****.com']);
            $message->subject($data['subject']);
        });
    }

我在这里犯了什么错误?

这是我的 mail.php 文件

<?php
return [ 
    'driver' => env('MAIL_DRIVER', 'smtp'),  
    'host' => env('MAIL_HOST', 'smtp.****.com'),
    'port' => env('MAIL_PORT', 587),
    'from' => [
        'address' => env('MAIL_FROM_ADDRESS', 'hello@example.com'),
        'name' => env('MAIL_FROM_NAME', 'Example'),
    ],   
    'encryption' => env('MAIL_ENCRYPTION', 'tls'),  
    'username' => env('MAIL_USERNAME'),
    'password' => env('MAIL_PASSWORD'), 
    'sendmail' => '/usr/sbin/sendmail -bs', 'markdown' => [
        'theme' => 'default',
        'paths' => [
            resource_path('views/vendor/mail'),
        ],
    ],
];

我用自己的代码替换了所有设置和代码,并且电子邮件已正确发送。我建议删除 composer.lock 文件并再次删除 vendor 目录和 运行 和 composer install。可能没有安装完整的包。
