首先我们在components文件夹下新建install.js文件

import aCom from './a.vue' import bCom from './b.vue' const allComponents = {     aCom,bCom } export default{     install(Vue){         console.log(Vue);         Object.keys(allComponents).forEach(key=>{             Vue.component(key,allComponents[key])             console.log(`Registered component: ${key}`);         })     } }

然后，我们在main.js中引入，就可以实现了

import globalComponents from '@/components/install.js' Vue.use(globalComponents)
