运行php artisan db：seed后，在laravel中找不到类'App \ Eloquent'

<?php

namespace App;

use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;

class User extends Eloquent implements UserInterface, RemindableInterface 
{

}

Your model should extend the Model class:

use Illuminate\Database\Eloquent\Model;
class User extends Model

If you want to use Laravel authentication system, it should extend Illuminate\Foundation\Auth\User:

use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
