我花了几个小时试图找出为什么作为全局变量的变量dataset_path总是未定义的原因

var dataset_path ;

function myFunction() {
  offline_data_mainlooper_bitfinex();
  print_bilan();
}
function offline_data_mainlooper_bitfinex(){
    var hours_step_size = 1*2;
    var daily_step_size = 24*2,
    // dataset_path = './quote/bitfinex/from_1480550400to_1512100800_1hquote.json';
    // dataset_path =  ('./quote/bitfinex/from_1480550400to_1512100800quote.json') //thats's 30 min
    dataset_path =  './quote/bitfinex/from_1480550400to_1512100800_15mquote.json'
       //... somecode


}
function print_bilan(){
   var filename = './analysis/test_log.json';
   //... somecode
 console.log('Quote saved! to ' +dataset_path, filename)
}
