微信小程序逆向重打包：_typeof3 is not a function

//这里是有问题的程序
function _typeof(o) {
    return "function" == typeof Symbol && "symbol" == typeof Symbol.iterator ? module.exports = _typeof = function(o) {
        return typeof o;
    } : module.exports = _typeof = function(o) {
        return o && "function" == typeof Symbol && o.constructor === Symbol && o !== Symbol.prototype ? "symbol" : typeof o;
    }, _typeof(o);
}
 
module.exports = _typeof;​

将这个文件里面的所有内容直接替换成下面的：

function _typeof2(o) {
  "@babel/helpers - typeof";
  return (_typeof2 = "function" == typeof Symbol && "symbol" == typeof Symbol.iterator ? function(o) {
      return typeof o;
  } : function(o) {
      return o && "function" == typeof Symbol && o.constructor === Symbol && o !== Symbol.prototype ? "symbol" : typeof o;
  })(o);
}
 
 
function _typeof(o) {
  return "function" == typeof Symbol && "symbol" === _typeof2(Symbol.iterator) ? module.exports = _typeof = function(o) {
      return _typeof2(o);
  } : module.exports = _typeof = function(o) {
      return o && "function" == typeof Symbol && o.constructor === Symbol && o !== Symbol.prototype ? "symbol" : _typeof2(o);
  }, _typeof(o);
}
 
 
module.exports = _typeof;​
