Laravel 5.4-未定义变量：降价

Question

I am trying to send a simple email with Laravel. I have no problem sending a normal HTML email but when I try to use the markdown feature I keep getting the error

Undefined variable: markdown

I am not using any instance of a model in my email right now, I am just trying to get a simple markdown email first. Here is how I have everything set up.

Mail Controller

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class ProjectSubmitted extends Mailable
{
    use Queueable, SerializesModels;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->markdown('emails.project-submitted');
    }
}

Blade Template

@component('mail::message')
*Lorem Ipsum Dolor

@component('mail::button', ['url' => 'http://google.com'])
Lorem Ipsum Dolor
@endcomponent

Thanks,<br>
Lorem Ipsum
@endcomponent

That is all I have right now, very basic. When I try to send this email

\\Mail::to('example@example.com')->send( new \\App\\Mail\\ProjectSubmitted );

I keep getting the error Undefined variable: markdown . Cannot find anything on this. Any help would be amazing.

This is an issue already reported here and patched very recently here .

A temporary fix can be applied by editing the Mailable.php file at the root of your project (/vendor/laravel/framework/src/Illuminate/Mail/Mailable.php).

Change line 195 to 'text' => $this->buildMarkdownText($markdown, $data) , and line 222 to protected function buildMarkdownText($markdown, $data) .
