build error with fibonacci_heap in Boost 1.71.0 and C++11 #39

It can build successfully with Boost 1.83.0 and C++14. But it build wrong with Boost 1.71.0 and C++11. How can I do if I don't update the version?

template <typename State, typename Action, typename Cost, typename Environment, typename StateHasher = std::hash<State> >
class AStar{
public:
/* other code */
private:
    struct Node {
        Node(const State& state, Cost fScore, Cost gScore)
            : state(state), fScore(fScore), gScore(gScore) {}

        bool operator<(const Node& other) const {
            // Sort order
            // 1. lowest fScore
            // 2. highest gScore

            // Our heap is a maximum heap, so we invert the comperator function here
            if (fScore != other.fScore) {
                return fScore > other.fScore;
            }
            else {
                return gScore < other.gScore;
            }
        }

        friend std::ostream& operator<<(std::ostream& os, const Node& node) {
            os << "state: " << node.state << " fScore: " << node.fScore
                << " gScore: " << node.gScore;
            return os;
        }

        State state;

        Cost fScore;
        Cost gScore;

        typename boost::heap::fibonacci_heap<Node>::handle_type handle;     // error with Boost 1.71.0 and C++11
        };
}
