Vue 應(yīng)用，IE瀏覽器（8--11）打不開，其他瀏覽器正常。IE打開就是空白。報錯如下：

/ harmony default export / __webpack_exports__["a"] = (function (instance, eventList) {
const ev = eventList || WEBPACK_IMPORTED_MODULE_0__events_js"a" / default /)(this.$options._componentTag)]
ev && ev.forEach(event => {

const hasOn = event.slice(0, 2) === 'on'
const eventName = hasOn ? event.slice(2) : event
const listener = this.$listeners[eventName]
listener && instance.addEventListener(event, listener.fns)

})
});
