php artisan db: семя не работает Laravel 5

Я прочитал другие ответы, но ничего не решило мою проблему. Когда я бегу php artisan db:seed ничего не происходит, даже не выдается ошибка.
Это мой класс DatabaseSeeder

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;

class DatabaseSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
Model::unguard();

// call our class and run our seeds
$this->call(BearAppSeeder::class);

// $this->call(UserTableSeeder::class);

Model::reguard();
}
}

BearAppSeeder содержит следующее содержание.

<?php

use Illuminate\Database\Seeder;

class BearAppSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
// clear our database ------------------------------------------
/*DB::table('bears')->delete();
DB::table('fish')->delete();
DB::table('picnics')->delete();
DB::table('trees')->delete();
DB::table('bears_picnics')->delete();*/

// seed our bears table -----------------------
// we'll create three different bears

// bear 1 is named Lawly. She is extremely dangerous. Especially when hungry.
$bearLawly = Bear::insert(['name'         => 'Lawly',
'type'         => 'Grizzly',
'danger_level' => 8]);

/*/ bear 2 is named Cerms. He has a loud growl but is pretty much harmless.
$bearCerms = Bear::create(array(
'name'         => 'Cerms',
'type'         => 'Black',
'danger_level' => 4
));

// bear 3 is named Adobot. He is a polar bear. He drinks vodka.
$bearAdobot = Bear::create(array(
'name'         => 'Adobot',
'type'         => 'Polar',
'danger_level' => 3
));

$this->command->info('The bears are alive!');

// seed our fish table ------------------------
// our fish wont have names... because theyre going to be eaten

// we will use the variables we used to create the bears to get their id

Fish::create(array(
'weight'  => 5,
'bear_id' => $bearLawly->id
));
Fish::create(array(
'weight'  => 12,
'bear_id' => $bearCerms->id
));
Fish::create(array(
'weight'  => 4,
'bear_id' => $bearAdobot->id
));

$this->command->info('They are eating fish!');

// seed our trees table ---------------------
Tree::create(array(
'type'    => 'Redwood',
'age'     => 500,
'bear_id' => $bearLawly->id
));
Tree::create(array(
'type'    => 'Oak',
'age'     => 400,
'bear_id' => $bearLawly->id
));

$this->command->info('Climb bears! Be free!');

// seed our picnics table ---------------------

// we will create one picnic and apply all bears to this one picnic
$picnicYellowstone = Picnic::create(array(
'name'        => 'Yellowstone',
'taste_level' => 6
));
$picnicGrandCanyon = Picnic::create(array(
'name'        => 'Grand Canyon',
'taste_level' => 5
));

// link our bears to picnics ---------------------
// for our purposes we'll just add all bears to both picnics for our many to many relationship
$bearLawly->picnics()->attach($picnicYellowstone->id);
$bearLawly->picnics()->attach($picnicGrandCanyon->id);

$bearCerms->picnics()->attach($picnicYellowstone->id);
$bearCerms->picnics()->attach($picnicGrandCanyon->id);

$bearAdobot->picnics()->attach($picnicYellowstone->id);
$bearAdobot->picnics()->attach($picnicGrandCanyon->id);

$this->command->info('They are terrorizing picnics!');*/

Я пробовал бегать composer dump-autoload но это не решило мою проблему. Я новичок в Laravel, поэтому я не знаю об этом слишком много.
