PHP Fatal error: Call to undefined method Illuminate\Foundation\Application::bindShared() in ..Entrust/EntrustServiceProvider.php on line 72

I've just installed Entrust to add Role-based Permissions to my application based on Laravel 5.2. But when I try to execute

php artisan vendor:publish

I get this error :

PHP Fatal error: " Call to undefined method Illuminate\Foundation\Application::bindShared() in ../vendor/zizaco/entrust/src/Entrust/EntrustServiceProvider.php on line 72 "

can anyone help me?
