Laravel: Specified key was too long error on migration


When you install a new Laravel project with ‘laravel new’ and run the migration that comes with it you might get following error:

#php artisan migrate
Migration table created successfully.


 [Illuminate\Database\QueryException]
 SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter table `users` add unique `users_email_unique`(`email`))

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

To solve this error edit your app/Providers/AppServiceProvider.php file.

Add the namespace:

use Illuminate\Support\Facades\Schema;

and then add the following line in boot() method of your AppServiceProvider class.

use Illuminate\Support\Facades\Schema;

class AppServiceProvider extends ServiceProvider
{
 /**
 * Bootstrap any application services.
 *
 * @return void
 */
 public function boot()
 {
   Schema::defaultStringLength(191);
 } 
}

This should solve your problem. Just delete all the tables and run the migration again.
