hash_map是C++非标准STL,因为标准化的推进,hash_map属于非标准容器,未来将要用unordered_map替代之。建议我们使用unorder_map替代hash_map,解决办法

(1)使用替换    或者

(2)加宏定义忽略这个错误

#define _SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS //添加这个宏定义即不报错
 #ifndef _SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS
static_assert(false, " is deprecated and will be REMOVED. "
	"Please use . You can define "
	"_SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS "

 #endif /* _SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS */
