c++ - 为什么它说#include包含在c++中时不包含？

Question

我是多线程的新手，但我在这个网站上找到了一个关于简单多线程代码的答案。我完全复制了它，#include <thread>但后来它在终端（我正在运行 Visual Studio Code）中说我没有包含线程。这是代码。

#include <string>
#include <iostream>
#include <thread>

using namespace std;

void task1(string msg)
{
    cout << "task1 says: " << msg;
}

int main()
{

    thread t1(task1, "Hello");

    t1.join();
}

这是我看到的错误：

c:\Users\Lol\Desktop\C++\Thread testing\Threadtest.cpp: In function 'int main()':
c:\Users\Lol\Desktop\C++\Thread testing\Threadtest.cpp:18:5: error: 'thread' was not declared in this scope

      |     ^~
      |     tm
The terminal process terminated with exit code: 1
