Answer 1

在运行“node index.js”之前，您是否运行了以下命令？

#include <tuple>
#include <utility>

template<typename...Rs>
struct S
{
    void store(std::tuple<Rs*...> rs)
    {
        rs_ = rs;
    }

    void store2(Rs*...rs)
    {
        rs_ = std::make_tuple<Rs*...>(rs...); // This is the guy that breaks
    }

private:
    std::tuple<Rs*...> rs_;
};

struct B
{};

struct A : S<B, B>
{};

int main()
{
    auto *b1 = new B;
    auto *b2 = new B;
    auto *a1 = new A;

    a1->store(std::make_tuple(b1, b2));   // This works
    a1->store2(b1, b2);    // How can I get this to work?
                           // (It causes an error in std::make_tuple of store2 above)
}

It must be an issue with an outdated version of node.js.

You could check the current version by typing in

node -v

I suppose it would output something like 0.8, which is pretty old.
