Facing a issue with Facade.php in migrate

I am using an existing project from GitHub, and I am trying to run Laravel very 1st time, but I am facing

In Connection.php line 664:

  SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes (S
  QL: alter table `users` add unique `users_email_unique`(`email`))

In Connection.php line 458:

  SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes

later I took some instructions and added use Illuminate\Support\Facades\Schema; under the AppServiceProvider.php but after adding I am getting a different error like

C:\wamp64\www\localseo>php artisan migrate

In Facade.php line 221:

  Call to undefined method Illuminate\Database\Schema\MySqlBuilder::defaultStringLenght()

Please help me how to avoid the error.
