c++ - “error: redefinition of class”，在同一行上

Question

我正在尝试导入我编写的.h文件，但出现以下错误:

$ g++ HeartRate.cpp
In file included from HeartRate.cpp:3:
In file included from ./HeartRate.h:2:
./Date.h:4:7: error: redefinition of 'Date'
class Date {
      ^
./Date.h:4:7: note: previous definition is here
class Date {
      ^
1 error generated.

这是我要导入的文件:

#include <iostream>
#include <string>

class Date {
    private:
        //...
    public:
        //...
};
