vite js 配置@路径

npm install @types/node --save-dev

vite.config.js

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
//需要引入
import path from 'path'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  resolve: {
    alias: {
      '@': path.resolve(__dirname, './src')
    }

  }
})

看看有没有jsconfig.json文件和src文件同级，没有就新建一个，然后把代码粘贴进入，配置就完成了
