能提供复现吗？

@sendya 不好意思，是我们这边的问题，组件引用顺序问题！感觉很奇怪，Number 会被修改掉(只有在ie浏览器，而且是打包后), Number.toString(): function(t){var e=arguments.length<1?0:t,n=this;return n instanceof O&&(x?h((function(){b.valueOf.call(n)})):c(n)!=m)?u(new y(w(e)),n,O):w(e)}; // 该函数 prototype —> Number;

Carousel props 初始参数 那里Number类型数据就会为undefined;

ant-design-vue —> lib —> _util —> utils.js 中 var getType = exports.getType = function getType(fn) { var type = fn !== null && fn !== undefined ? fn.type ? fn.type : fn : null; var match = type && type.toString().match(FN_MATCH_REGEXP); return match && match[1]; }; // 造成 match[1] 为undefined 所以赋值default: undefined, 走马灯出错

如果 Carousel 组件 先于 Vuedraggable 引入 就不会 造成 Number 修改问题；
