Laravel 5.7 showing “Failed to clear cache. Make sure you have the appropriate permissions”

Laravel 5.7 showing “Failed to clear cache. Make sure you have the appropriate permissions”

Got error while running “php artisan cache:clear”

Solution:

If the “data” directory (storage/framework/cache/data) doesn’t exist you will have this error.
This “data” folder doesn’t exist by default on a fresh/new installation.
Creating the “data” directory at (storage/framework/cache) manually should fix this issue.
