Some Solution that worked for me: (Try running command after config:clear and
                                   try migrate:fresh)
1. added default string length:

use Illuminate\Support\Facades\Schema;

public function boot()
{
    Schema::defaultStringLength(191);
}

2. changing engine to 'InnoDB' inside /config/database.php
  
'mysql' => [
    ...,
    ...,
    'engine' => 'InnoDB',
 ]
  
3. If still not solved try updating 'charset' and 'collation' inside 
  /config/database.php
  
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',

to

'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
