It seems like you code against a concrete implementation and not the interface Symfony\Component\Console\Output\OutputInterface as the method isVerbose() does only exist in the following implementations of said interface: BZIon\Command\NullOutput, Symfony\Component\Console\Output\BufferedOutput, Symfony\Component\Console\Output\ConsoleOutput, Symfony\Component\Console\Output\NullOutput, Symfony\Component\Console\Output\Output, Symfony\Component\Console\Output\StreamOutput, Symfony\Component\Console\Tests\Fixtures\DummyOutput, Symfony\Component\Console\Tests\Output\TestOutput.

            return null;
        }

        return function ($type, $buffer) {
            if (Process::ERR === $type) {
                echo 'ERR > ' . $buffer;
            } else {
                echo 'OUT > ' . $buffer;
            }
        };
    }
}
