问题: Vue 无法渲染

[Vue warn]: Failed to resolve component: router-view

排查

import { createApp } from 'vue'
import App from './App.vue'
import router from './router.js'

createApp(App).mount('#app')

const AppVue = createApp(App)
AppVue.use(router).mount('#app')

Vue.mount('#app') 一定要在最后

解决

import { createApp } from 'vue'
import App from './App.vue'
import router from './router.js'

const AppVue = createApp(App)
AppVue.use(router).mount('#app')
