 ERROR  Failed to compile with 2 errors                                                                                                       上午8:55:30

These dependencies were not found:

* element-plus/lib/el-button in ./src/global/register-element.ts
* element-plus/lib/el-input in ./src/global/register-element.ts

To install them, you can run: npm install --save element-plus/lib/el-button element-plus/lib/el-input

问题原因：
文件导入方式错误

// import 'element-plus/theme-chalk/index.css'
// import { ElButton, ElInput } from 'element-plus'

问题解决：
按照官方提供的按需加载方式

// 导入index.css
import 'element-plus/dist/index.css'
// 局部导入的路径
import { ElButton, ElInput } from 'element-plus/lib/components'
