I try using Vue 3, but I look can't using Vue.use(exampleplugin) again.
I using command vue add bootstrap-vue after generate vue create project. And on plugin bootstrap-vue warning with code:
import Vue from "vue";
import BootstrapVue from "bootstrap-vue";
import "bootstrap/dist/css/bootstrap.min.css";
import "bootstrap-vue/dist/bootstrap-vue.css";
Vue.use(BootstrapVue);
Output warning terminal:
warning in ./src/plugins/bootstrap-vue.js
"export 'default' (imported as 'Vue') was not found in 'vue'
warning in ./node_modules/bootstrap-vue/esm/utils/vue.js
"export 'default' (imported as 'Vue') was not found in 'vue'
What's wrong with that? And how do I use vue 3 to add plugin bootstrap-vue?
Bootstrap Vue is not yet ready for Vue 3.
To answer part of your question, Vue 3 changes the method for instantiating the application instance, including how plugins are registered.
For example...
import { createApp } from 'vue';
import Router from './router/Router';
createApp({/* options */}})
.use(Router)
.mount('#app');
