如何声明无序映射和字符串向量的unordered_map？

问：

我正在尝试并得到以下代码

#include <unordered_map>
#include <vector>
#include <string>
using namespace std;

int main() {
    unordered_map<char, int> myMap;
    vector<string> myVector;
    unordered_map<unordered_map<char, int>, vector<string>> myUnorderedMap;
    myUnorderedMap[myMap] = myVector;
    return 0;
}

我收到以下错误：

main.cpp: In function ‘int main()’:
main.cpp:9:61: error: use of deleted function ‘std::unordered_map\<\_Key, \_Tp, \_Hash, \_Pred, \_Alloc\>::unordered_map() \[with \_Key = std::unordered_map; \_Tp = std::vector \>; \_Hash = std::hash \>; \_Pred = std::equal_to \>; \_Alloc = std::allocator, std::vector \> \> \>\]’

我正在尝试在 c++ 中创建无序映射和字符串向量的unordered_map 类似的东西unordered_map<unordered_map<char, int>, vector<string>> myUnorderedMap;
