Why is magento2 throwing an error?

Question

Magento

I downloaded and uploaded magento2 to localhost, everything seems to work, but with any command (let's say sudo php bin/magento cache:flush) gives the same error

Deprecated Functionality: The each() function is deprecated. This message will be suppressed on further calls in /var/www/html/vendor/colinmollenhour/cache-backend-file/File.php on line 81

//php7.1, apache 2.4

Check that you are running 7.1 from the console, not 7.2
