This method seems to be duplicated in your project.

It seems like you code against a concrete implementation and not the interface Symfony\Component\Console\Output\OutputInterface as the method getErrorOutput() does only exist in the following implementations of said interface: Psy\Output\ShellOutput, Symfony\Component\Console\Output\ConsoleOutput.
