我有一个 .ini 文件包含以下数据
[SYSTEM]
num_of_vps = 1
我有这段代码来读取 .ini 文件中的元素。（uint定义为typedef unsigned int uint）
boost::property_tree::ptree pt;
boost::property_tree::ini_parser::read_ini(iniFilePath, pt);
hwCount = pt.get<uint>("SYSTEM.num_of_vps");
我从包含上述代码的文件创建了一个文件，并在文件中的包装函数中调用了它main.cc。然后我收到以下错误
抛出 'boost_1_68_0::exception_detail::clone_impl<boost_1_68_0::exception_detail::error_info_injector<boost_1_68_0::property_tree::ptree_bad_data> >' 实例后调用的终止what()：将数据转换为类型“j”失败的堆栈跟踪
