Whenever I open a file (in PHP Storm), an error message appears.
phpcs: ERROR: Referenced sniff "SlevomatCodingStandard.Arrays.TrailingArrayComma" does not exist
Run "phpcs --help" for usage information
Don’t know why? How to fix it?
I’m guessing that you’ve got a code sniffer extension enabled, but incorrectly configured.
I deleted path in phpstorm and no message yet.
could it be that you have phpcs globally installed? Try to make phpstorm use phpcs from the vendor/bin folder
Another solution could be install dealerdirect/phpcodesniffer-composer-installer
