Compiled Services Class Has been removed Composer error laravel 5.4

The message The compiled services file has been removed. is a info message from the clear compiled command: php artisan clear-compiled.

It is called from php artisan optimize that runs on every composer update or install.

The message is only a info reporting that the file bootstrap/cache/services.php has been removed.

The services.php file will be reconstructed at the next request.

So at the end its a normal info message.
