Problem using first artisan migrate in Laravel 5.4

[strikermdd]

Hi, i´m trying to install this package in a clean laravel 5.4 install and using utf8-mb4 database, and it gives me this error:

[Illuminate\Database\QueryException]
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter tabl
e roles add unique roles_name_unique(name))

[PDOException]
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes

Its necessary to change something to be able to work with this database collation in Laravel 5.4 and your package migration?
