The method share() does not exist on Psr\Container\ContainerInterface. It seems like you code against a sub-type of Psr\Container\ContainerInterface such as League\Container\Container.

        $this->container->share(NodePrinterInterface::class, NodePrinter::class);
        $this->container->add(ParserInterface::class, Parser::class);

The method add() does not exist on Psr\Container\ContainerInterface. It seems like you code against a sub-type of Psr\Container\ContainerInterface such as League\Container\Container.
