C++编译错误:没有用于初始化的匹配构造函数

我在编译C++时遇到了问题。也就是说,我从标题中得到以下模糊错误:

In file included from .../map.test.cpp:1:
/Library/Developer/CommandLineTools/usr/include/c++/v1/memory:2172:15: error: no matching constructor for initialization of
  'SmallWorld::Map::Graph<SmallWorld::Region>'
          __second_(_VSTD::forward<_Args2>(_VSTD::get<_I2>(__second_args))...)

相关代码如下:

#include <memory>
#include <string>
#include <gtest/gtest.h>
#include "../../../app/Domain/Map/loader.cpp"

using std::string;

TEST(creates_a_connected_graph, small_world_map){
  using SmallWorld::Region;
  using Graph = SmallWorld::Map::Graph<Region>;
  using search_set = std::set<string>;
  using forest_map = std::unordered_map<string, std::pair<string, string>>;

  std::shared_ptr<Graph> g = SmallWorld::Map::loadMap("./map.json");
  const size_t order = g->order();
  const size_t dfs_order = SmallWorld::Map::algorithm::dfs<Region>(
    "r1",
    [](const string&, const search_set&, const forest_map&) -> bool { return true; }
  )(*g);
  ASSERT_EQ(order, dfs_order);
};

其中,故障线路最有可能出现在shared\u ptr实例化处。对loadMap的调用调用以下函数:

std::shared_ptr<Map::Graph<Region>> loadMap(const string& path, const string& schema = "./map.ajv.json") {
      using Graph = SmallWorld::Map::Graph<Region>;
      using region_ptr = std::shared_ptr<Region>;
      json* map = readMap(path, schema);
      std::vector<std::pair<string, region_ptr>> regions = extractRegions(*map);
      std::vector<std::pair<string, string>> edges = extractEdges(*map);
      std::shared_ptr<Graph> pgraph = std::make_shared<Graph>(new Graph(regions, edges));
      delete map;
      return pgraph;
    };

以及我唯一的Graph类用户定义构造函数:

Graph<E>(std::vector<std::pair<string, std::shared_ptr<E>>> nodes, std::vector<std::pair<string, string>> edges);

设置:

• 操作系统: MacOS 10.13.3
• C++版本: 14
• 编译器: g++=>Apple LLVM 9.0.0版(clang-900.0.39.2)

我已经在CMAKE\u CXX\u标志中添加了verbose标志,以查看是否可以获得类似于编译错误的堆栈跟踪的内容,但没有效果。这很可能是重复的。如果你有办法解决这个问题,那就太好了;如果您知道一种为编译错误获取堆栈跟踪类错误的方法,那么您就是我的救世主<3.
