laravel-permission: PermissionAlreadyExists - A `users_manage` permission already exists for guard `web`.

I had to clear the permission cache!

Running:

php artisan cache:forget spatie.permission.cache
php artisan cache:clear  

Got me going again! Thank you

https://github.com/spatie/laravel-permission/issues/231

Help for me:

sudo php artisan cache:forget spatie.permission.cache && sudo php artisan cache:clear

sudo chmod 777 -R /var/www/html/project/storage/

Try php artisan migrate:refresh --seed. Also ensure in your PermissionSeed that you are ONLY defining one instance of users_manage. Let me know how it goes!

OR you can paste your PermissionSeed here so we can see if the problem is in there.

php artisan cache:forget spatie.permission.cache php artisan cache:clear

Same issue on Laravel 7.1X when I tried to refresh the migrations, and this worked for me:

sudo chmod 777 -R /var/www/project/storage/
php artisan cache:forget spatie.permission.cache
php artisan cache:clear
php artisan db:seed --class=YourSeederClass

Better to use php artisan permission:cache-reset as documented https://docs.spatie.be/laravel-permission/v3/advanced-usage/cache/

Besides the clearing of the cache and all that, try to check if permissions and roles already exist. This way you can run your seeder as often as you like without errors … even extend it and rerun it, if you forgot something 😉

try {
	$a_role = Role::findByName('my_role');
} catch (Exception $e) {
	$a_role = Role::create(['name' => 'my_role']);
}

and

try {
	$a_permission = Permission::create(['name' => 'my_permission']);
} catch (Exception $e) {
	$a_permission = 'my_permission';
}

and

if (!$a_role->hasPermissionTo($a_permission)) {
	$a_role->givePermissionTo($a_permission);
}
