安装环境@vue/cli 4.5.13

1、创建vue3.x项目，执行如下命令

vue create 项目名称

项目创建成功后，我们首先需要根目录下添加vue配置vue.config.js，内容如下：

module.exports = {
    devServer: {
        open: true,
    }
}

2、启动项目，执行指令如下

npm run serve

命令执行完毕之后，会在默认浏览器中打开项目，至此项目启动成功！效果如下

3，安装element-plus，执行指令如下

npm install element-plus --save

安装完成之后，这里我们选择按需引入的方式引入项目，按需引入借助 babel-plugin-import，我们可以只引入需要的组件，以达到减小项目体积的目的，执行指令如下：

npm install babel-plugin-import -D

然后，将 babel.config.js 修改为：

module.exports = {
  plugins: [
    [
      "import",
      {
        libraryName: 'element-plus',
        customStyleName: (name) => {
          return `element-plus/lib/theme-chalk/${name}.css`;
        },
      },
    ],
  ],
};

在src目录下面新增一个文件夹utils并创建elementPlus.js存放需要引入的组件，需要什么组件按需添加就好了，下面我放了完整的组件列表

    ElUpload,
]

export const plugins = [
    ElInfiniteScroll,
    ElLoading,
    ElMessage,
    ElMessageBox,
    ElNotification,
]

修改main.js内容如下：

import { createApp } from 'vue'
import App from './App.vue'
import {
    components,
    plugins
} from './utils/elementPlus.js'

const app = createApp(App)
components.forEach(component => {
    app.component(component.name, component)
})

plugins.forEach(plugin => {
    app.use(plugin)
})
app.mount('#app')
