IE 11 polyfill-eventsource 将缺少的 EventSource 添加到窗口

如何解决IE 11 polyfill-eventsource 将缺少的 EventSource 添加到窗口

我来自韩国，那里的 Internet Explorer 份额非常高。

在使用 Nuxt 构建网站时，IE 突然开始出现 [对象错误]。但我不知道究竟是什么导致了这个问题。

这是我的nuxt.config.js

import config from './configs'

const { gaId } = config.analytics

运行Npm Run Dev后，点击页面列表中的某个页面导致上述错误。不知道是哪个问题
