Why can't I compile an unordered_map with a pair as key?

I am trying to create an unordered_map to map pairs with integers: #include <unordered_map> using namespace std; using Vote = pair<string, string>; using Unordered_map = unordered_map<Vote, int>; I have a class where I have declared an Unordered_map as a private member. However, I am getting the following error when I try to compile it: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/type_traits:948:38: Implicit instantiation of undefined template 'std::__1::hash, std::__1::basic_string > >' I am not getting this error if I use a regular map
