我应该怎样更好的修改内部组件代码。

是根据这个文档吗：https://vitepress.dev/zh/guide/extending-default-theme#overriding-internal-components

使用 Vite 的 aliases 来用自定义组件替换默认主题的组件

主要是替换为自定义的组件

1. 如果只是小改动，可以参考本仓库的源码将组件复制到仓库进行改动（且 import 路径可以选择原 vitepress，可以选择使用自己的）https://github.com/vuejs/vitepress/blob/main/src/client/theme-default/components/VPNavBar.vue
2. 当然你也可以在源码找到需要修改的内部组件，进行替换

<script lang="ts" setup>
import { useWindowScroll } from '@vueuse/core'
import { ref, watchPostEffect } from 'vue'
import { useData } from 'vitepress/dist/client/theme-default/composables/data'
import { useSidebar } from 'vitepress/dist/client/theme-default//composables/sidebar'
import VPNavBarAppearance from 'vitepress/dist/client/theme-default/components/VPNavBarAppearance.vue'
import VPNavBarExtra from 'vitepress/dist/client/theme-default/components/VPNavBarExtra.vue'
import VPNavBarHamburger from 'vitepress/dist/client/theme-default/components/VPNavBarHamburger.vue'
import VPNavBarMenu from 'vitepress/dist/client/theme-default/components/VPNavBarMenu.vue'
import VPNavBarSearch from 'vitepress/dist/client/theme-default/components/VPNavBarSearch.vue'
import VPNavBarSocialLinks from 'vitepress/dist/client/theme-default/components/VPNavBarSocialLinks.vue'
import VPNavBarTitle from 'vitepress/dist/client/theme-default/components/VPNavBarTitle.vue'
import VPNavBarTranslations from 'vitepress/dist/client/theme-default/components/VPNavBarTranslations.vue'

const props = defineProps<{
  isScreenOpen: boolean
}>()

我这个是直接将官方源码复制过来知识修改了import 然后在config使用vite替换官方的内部组件

这里quan's全是空白
