'getline' 未在此范围内声明，这是什么意思？

Question

编译时，我 'getline' 没有在此范围内声明

编译下一个代码：

string PostCmd::getFailedFromFile()
{
    string failedList;
    ifstream file(FILE, ifstream::in);
    if (file.is_open())
    {
        getline(file, failedList);
        file.close();
    }
    else
    {
        cout << "Unable to open file";
    }
    return failedList;
}

Answer 1

尝试包含 <istream>.

'getline' was not declared in this scope, what does it mean?
