It seems like $this->input->getArgument('name') ?? $this->getBinary() can also be of type string[]; however, parameter $name of LaravelZero\Framework\Commands\BuildCommand::build() does only seem to accept string, maybe add an additional type check?

The method section() does not exist on Symfony\Component\Console\Output\OutputInterface.
