微信小程序源码开发：app.js错误：typerror:typeof3 is not a function

修改一下 @babel\runtime\helpers\typeof.js

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;
