插入指向向量的指针时出错

    struct node{
            char charVal;
            bool childNode;
            struct node *leftChild;
            struct node *rightChild;
    };
    vector<std::pair<int,struct node*> > nodeCountList;
    struct node *nodePtr = new struct node;
    nodeCountList.push_back(1,nodePtr); 

错误消息

error: no matching function for call to ‘std::vector<std::pair<int, node*>, std::allocator<std::pair<int, node*> > >::push_back(int&, node*&)’
/usr/lib/gcc/i386-redhat-linux/4.1.2/../../../../include/c++/4.1.2/bits/stl_vector.h:602: note: candidates are: void std::vector<_Tp, _Alloc>::push_back(const _Tp&) [with _Tp = std::pair<int, node*>, _Alloc = std::allocator<std::pair<int, node*> >]

请帮助我排除错误消息的故障。

干杯
