Namespace std does not name a template type C++

This code was working just yesterday, but it broke today and I can't figure it out. Spent a lot of time setting up C++ last night and to have it not work on me right now is a bit frustrating; here's the code

/*
 * PlayerEntity.h
 *
 *  Created on: Jan 28, 2017
 *      Author: Jon
 */

#ifndef PLAYERENTITY_H_
#define PLAYERENTITY_H_

#include "GameEntity.h"
#include <map>
#include <utility>

class PlayerEntity: public GameEntity {
public:
    PlayerEntity();
    virtual ~PlayerEntity();

    int size();

    void grow();

private:
    int length;
    std::pair<int, int> head, tail, direction;
    std::map<int, std::pair<int, int>> directions;
};

#endif /* PLAYERENTITY_H_ */

The error is this:

'map' in namespace 'std' does not name a template type

'pair' in namespace 'std' does not name a template type

Steps Taken - Include utility - Include map - Clean project
