一、警告信息如下：
vue+element项目中，解决chrome下的passive警告问题

element-ui.common.js?5c96:9972 [Violation] Added non-passive event listener to a scroll-blocking 'mousewheel' event. Consider marking event handler as 'passive' to make the page more responsive. See https://www.chromestatus.com/feature/5745543795965952

二、问题解决
安装 default-passive-events
yarn add default-passive-events

在main.js中引入即可
import "default-passive-events"; //添加事件管理者'passive'，来阻止'touchstart'事件，让页面更加流畅。 解决chrome下的warning问题
