Uncaught DOMException: Failed to read the 'cssRules' property from 'CSSStyleSheet': Cannot access rules

vue3+vue-router4在使用过程中，通过composition api watch对router对象进行监听时，会出现这个问题。

import { useRoute } from 'vue-router'
const route = useRoute()
watch(
      route,
      (to, from) => {
        // do something
      }
    )

解决办法，别监听整个router对象，改为监听其某个属性，如监听path的变化就可以了。

Uncaught (in promise) DOMException: Failed to read the 'value' property from 'SVGLength': Could not resolve relative length.

项目中用到了svg，同时做了svg根据主题色进行换色处理的功能(监听了路由的变化去处理)，打包部署后出现这个问题，解决办法如第一个。
